In MSM architecture, the DBM, Device Bus Manager, is a HW module within
the USB3.0 core wrapper, implementing BAM interface support for USB3.0 IP.
The DBM HW unit requires for its operation a special transfer to be
started, with special TRBs structure. These usb requests will operate in
BAM2BAM mode.
This change adds to the dwc3-msm.c driver a support for queuing
a special transfers to endpoints which serve the DBM.
A function driver can now call to msm_ep_config(*ep) with some
endpoint which will serve the DBM. After this, the function
driver can queue a request to this endpoint as usual ep->queue(*ep,*req).
The function driver may need to add a few more parameters in req->udc_priv
field according to the bit mask fields defined in msm_hsudb.h file.

The req->udc_priv value is used to transfer parameters from a function
driver to a udc, for enabling sps/bam mode for MSM architecture.
This change moves the definitions of the bit fields inside the udc_priv to
msm_hsusb.h in order to avoid duplicate definitions in u_bam.c and
ci13xxx_udc.h. Also this will allow other function drivers and other udcs
to use this definitions, for example, debug class over dwc3 udc.

Drivers need to specify their bandwidth requirements to
bus-scaling driver to get guaranteed bandwidth on fabrics.
HSIC USB performance depends upon system fabric frequency
as HSIC USB controller has to support high bi-directional
data transfers. Hence, request for high bus bandwidth as
long as HSIC is active.
Also add debugfs entry to enable/disable the bus voting:-

This reverts commit 7dd2266ae3.
It was a mistake to move the usb driver to the clock apis for XO
buffer voting. Due to an RPM design CXO and D0 are the same but
we would like to hide that from the users of the buffers.
Therefore the msm_xo driver itself remaps the D0 buffer request
to the cxo clock until the RPM is fixed.

usb: gadget: storage: fix mass storage gadgets to work with Synopsys UDC
The Synopsys USB device controller requires all OUT transfer request
lengths to be aligned to max packet size. The mass storage gadgets do
not meet this requirement for Super Speed. The gadgets already have a
function which performs this alignment for CBW packets, so use it for
data packets too.
The alternative would be to implement bounce buffers in the DWC3
driver, but that could have a significant impact on performance.
This version is based upon a more-correct patch written by Alan
Stern.

USB: gadget: storage: remove alignment assumption
This patch (as1481) fixes a problem affecting g_file_storage and
g_mass_storage when running at SuperSpeed. The two drivers currently
assume that the bulk-out maxpacket size can evenly divide the SCSI
block size, which is 512 bytes. But SuperSpeed bulk endpoints have a
maxpacket size of 1024, so the assumption is no longer true.
This patch removes that assumption from the drivers, by getting rid of
a small optimization (they try to align VFS reads and writes on page
cache boundaries). If a command's starting logical block address is
512 bytes below the end of a page, it's not okay to issue a USB
command for just those 512 bytes when the maxpacket size is 1024 -- it
would result in either babble (for an OUT transfer) or a short packet
(for an IN transfer).
Also, for backward compatibility, the test for writes extending beyond
the end of the backing storage has to be changed. If the host tries
to do this, we should accept the data that fits in the backing storage
and ignore the rest. Because the storage's end may not align with a
USB packet boundary, this means we may have to accept a USB OUT
transfer that extends beyond the end of the storage and then write out
only the part of the data that fits.

Date: Wed Aug 17 22:52:59 2011 -0700
usb: gadget: storage: adapt logic block size to bound block devices
Now the mass storage driver has fixed logic block size of 512 bytes.
The mass storage gadget read/write bound devices only through VFS, so the
bottom level devices actually are just RAW devices to the driver and connected
PC. As a RAW, hosts can always format, read and write it right in 512 bytes
logic block and don't care about the actual logic block size of devices bound
to the gadget.
But if we want to share the bound block device partition between target board
and PC, in case the logic block size of the bound block device is 4KB, we
execute the following steps:
1. connect a board with mass storage gadget to PC(the board has set one
partition of on-board block device as file name of the mass storage)
2. PC format the mass storage to VFAT by default logic block size and
read/write it
3. disconnect boards from PC
4. target board mount the partition as VFAT
Step 4 will fail since kernel on target thinks the logic block size of the
bound partition as 4KB.
A typical error is "FAT: logical sector size too small for device (logical
sector size = 512)"
If we execute opposite steps:
1. format the partition to VFAT on target board and read/write this partition
2. connect the board to Windows PC as usb mass storage gadget, windows will
think the disk is not formatted
So the conclusion is that only as a gadget, the mass storage driver has no any
problem. But being shared VFAT or other filesystem on PC and target board, it
will fail.
This patch adapts logic block size to bound block devices and fix the issue.

usb: gadget: epautoconf: do not change number of streams
We should not change gadget driver's descriptors just
because we think it's right to do so.
There are several of reasons which would support this
statement but it suffices to say that this was probably
never tested because it updates bmAttributes without
asking the driver if it's ok to do so.
This means that e.g. on UASP gadget it would enable
stream support even for the command endpoint which must
not have stream support enabled.
In fact, this change is fixing the bug introduced by
commit a59d6b9 (usb: gadget: add streams support to
the gadget framework) which was caught when testing
UASP gadget with dwc3 driver.

usb: gadget: defer setting maxpacket till ->setup()
maxpacket is set by the udc driver for ep0 very early. This value is
copied by the function gadget used later for the USB_DT_DEVICE and
USB_DT_DEVICE_QUALIFIER query. This seems to work fine so far. For USB3
we need set a different value here. In SS speed it is 2^x with x=9 and
in HS we set something <= 64. If the UDC starts in SS and continues in
HS after the cable has been plugged it will report a too small value.
There setting of this value is defered and taken automaticly from the
ep0 pointer where the UDC driver can update it according to the speed it
detected _after_ a cable has been plugged.

Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date: Tue Jun 28 16:33:47 2011 +0300
usb: gadget: convert all users to the new udc infrastructure
peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
register/unregister to the udc-core.
The udc-core will take the first available gadget driver and attach
function driver which is calling usb_gadget_register_driver(). This is
the same behaviour we have right now.
Only dummy_hcd was tested, the others were compiled tested.

commit 5177504241
Author: Felipe Balbi <balbi@ti.com>
Date: Tue Jun 28 16:33:46 2011 +0300
usb: gadget: introduce UDC Class
this class will be used to abstract away several of the duplicated
operations scattered among the USB gadget controller drivers.
Later, we can add an atomic notifier to tell interested drivers about
what's happening with the controller. Notifications such as suspend,
resume, enumerated, etc. will be useful, at a minimum, for implementing
usb charger detection.
As part of the converting process usb_gadget_probe_driver() is no longer
part of each udc but pushed into the ->stap() callback. The same for his
couterpart.
The core is currently set explicit to 'n'. It will be changed to 'y' once
all users are converted since it provides functions which clash with
other drivers.

usb: dwc3: gadget: replace mdelay with udelay in the busy loop
There are two spots where we wait until the HW finishes processing a
certain command. Initially we had a few problems and we used 500ms as a
limit to be on a the safe side. Paul Zimmerman mentioned this is little too
much. After a debugging session, we noticed that we hardly ever go over 20us
and didn't pass 30usec so far. Using mdelay() seems way overloaded.
Giving the current numbers 500usec as the upper limit is more than enough.
Should it ever timeout then something is definitely wrong.
While here, also replace the type with u32 since long does not really
fit here.

usb: dwc3: gadget: rework the dequeue on RESET & DISCONNECT
- since a while we are disabling an endpoint and purging every requests on
RESET and DISCONNECT which leads to a warning since the endpoint was
disabled twice (once by the UDC, and second time by the gadget). I
think UDC should nuke all requests because all those requests
become invalid. It's gadget driver's responsability, though, to disable
its used endpoints. This is done by merging dwc3_stop_active_transfer()
and dwc3_gadget_nuke_reqs() into dwc3_remove_requests().
- dwc3_stop_active_transfer() is now no longer called unconditionaly.
This has the advantage that it is always called to disable an active
transfer which means if res_trans_idx 0 than something went wrong and
it is an error condition because we can't clean up the requests.
- Remove the DWC3_EP_WILL_SHUTDOWN which was introduced while
introducing the command complete part for dequeue. All requests on
req_queued list should be removed during the dwc3_cleanup_done_reqs()
callback so there is no reason to go through the list again.
We consider it an error condition if requests are still on this
list since we never queue TRB without LST=1 (the last requests has
always LST=1, there are no requests with LST=0 behind it).

usb: dwc3: ep0: simplify EP0 state machine
The DesignWare USB3 core tells us which phase
of a control transfer should be started, it
also tells us which physical endpoint needs
that transfer.
With these two informations, we have all we
need to simply EP0 handling quite a lot and
get rid rid of the SW state machine tracking
ep0 states.
For achieving this perfectly, we needed to
add support for situations where we get
XferNotReady while endpoint is still busy
and XferNotReady while gadget driver still
hasn't queued a request.

usb: dwc3: Introduce DesignWare USB3 DRD Driver
The DesignWare USB3 is a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.
Several other parameters can be configured
like amount of FIFO space, amount of TX and
RX endpoints, amount of Host Interrupters,
etc.
The current driver has been validated with
a virtual model of version 1.73a of that core
and with an FPGA burned with version 1.83a
of the DRD core. We have support for PCIe
bus, which is used on FPGA prototyping, and
for the OMAP5, more adaptation (or glue)
layers can be easily added and the driver
is half prepared to handle any possible
configuration the HW engineer has chosen
considering we have the information on
one of the GHWPARAMS registers to do
runtime checking of certain features.
More runtime checks can, and should, be added
in order to make this driver even more flexible
with regards to number of endpoints, FIFO sizes,
transfer types, etc.
While this supports only the device side, for
now, we will add support for Host side (xHCI -
see the updated series Sebastian has sent [1])
and OTG after we have it all stabilized.

This patch fixes the following OTG related bugs:
1. The current code does not wait for the ongoing HNP polling work to
finish upon the device disconnection which results in a crash when
accessing the udev structure in hnp polling routine.
2. bcdOTG field is added to OTG descriptor in 2.0 revision. Check OTG
descriptor size before validating bcdOTG field. A legacy device sends
2 bytes lesser than the size of OTG descriptor specified in 2.0 spec.
3. The host is required to execute a GetStatus() with a frequency of
THOST_REQ_POLL in order to determine the state of the Host request flag.
The limits of THOST_REQ_POLL are 1 - 2 sec. Use the average value 1.5 sec
for HNP polling to pass compliance tests.

this class will be used to abstract away several of the duplicated
operations scattered among the USB gadget controller drivers.
Later, we can add an atomic notifier to tell interested drivers about
what's happening with the controller. Notifications such as suspend,
resume, enumerated, etc. will be useful, at a minimum, for implementing
usb charger detection.
As part of the converting process usb_gadget_probe_driver() is no longer
part of each udc but pushed into the ->stap() callback. The same for his
couterpart.
The core is currently set explicit to 'n'. It will be changed to 'y' once
all users are converted since it provides functions which clash with
other drivers.

Drivers need to specify their bandwidth requirements to
bus-scaling driver to get guaranteed bandwidth on fabrics.
USB hardware uses a single buffer to transfer data across the
bus. As a result USB performance is highly dependent on system
fabric frequency as USB controller continuously sends NAKs on
the USB BUS unless complete buffer is filled/drained to the memory.
Hence, request for high bus bandwidth as long as USB cable is
connected to improve USB throughput.
While testing with Class-10 Extreme III SD cards, this patch
seems to improve the IN performance from 15MBps to 24MBps and
OUT performance from 11MBps to 16MBps.

usb: gadget: storage: fix mass storage gadgets to work with Synopsys UDC
The Synopsys USB device controller requires all OUT transfer request
lengths to be aligned to max packet size. The mass storage gadgets do
not meet this requirement for Super Speed. The gadgets already have a
function which performs this alignment for CBW packets, so use it for
data packets too.
The alternative would be to implement bounce buffers in the DWC3
driver, but that could have a significant impact on performance.
This version is based upon a more-correct patch written by Alan
Stern.

USB: gadget: storage: remove alignment assumption
This patch (as1481) fixes a problem affecting g_file_storage and
g_mass_storage when running at SuperSpeed. The two drivers currently
assume that the bulk-out maxpacket size can evenly divide the SCSI
block size, which is 512 bytes. But SuperSpeed bulk endpoints have a
maxpacket size of 1024, so the assumption is no longer true.
This patch removes that assumption from the drivers, by getting rid of
a small optimization (they try to align VFS reads and writes on page
cache boundaries). If a command's starting logical block address is
512 bytes below the end of a page, it's not okay to issue a USB
command for just those 512 bytes when the maxpacket size is 1024 -- it
would result in either babble (for an OUT transfer) or a short packet
(for an IN transfer).
Also, for backward compatibility, the test for writes extending beyond
the end of the backing storage has to be changed. If the host tries
to do this, we should accept the data that fits in the backing storage
and ignore the rest. Because the storage's end may not align with a
USB packet boundary, this means we may have to accept a USB OUT
transfer that extends beyond the end of the storage and then write out
only the part of the data that fits.

usb: gadget: storage: adapt logic block size to bound block devices
Now the mass storage driver has fixed logic block size of 512 bytes.
The mass storage gadget read/write bound devices only through VFS, so the
bottom level devices actually are just RAW devices to the driver and connected
PC. As a RAW, hosts can always format, read and write it right in 512 bytes
logic block and don't care about the actual logic block size of devices bound
to the gadget.
But if we want to share the bound block device partition between target board
and PC, in case the logic block size of the bound block device is 4KB, we
execute the following steps:
1. connect a board with mass storage gadget to PC(the board has set one
partition of on-board block device as file name of the mass storage)
2. PC format the mass storage to VFAT by default logic block size and
read/write it
3. disconnect boards from PC
4. target board mount the partition as VFAT
Step 4 will fail since kernel on target thinks the logic block size of the
bound partition as 4KB.
A typical error is "FAT: logical sector size too small for device (logical
sector size = 512)"
If we execute opposite steps:
1. format the partition to VFAT on target board and read/write this partition
2. connect the board to Windows PC as usb mass storage gadget, windows will
think the disk is not formatted
So the conclusion is that only as a gadget, the mass storage driver has no any
problem. But being shared VFAT or other filesystem on PC and target board, it
will fail.
This patch adapts logic block size to bound block devices and fix the issue.

usb: gadget: epautoconf: do not change number of streams
We should not change gadget driver's descriptors just
because we think it's right to do so.
There are several of reasons which would support this
statement but it suffices to say that this was probably
never tested because it updates bmAttributes without
asking the driver if it's ok to do so.
This means that e.g. on UASP gadget it would enable
stream support even for the command endpoint which must
not have stream support enabled.
In fact, this change is fixing the bug introduced by
commit a59d6b9 (usb: gadget: add streams support to
the gadget framework) which was caught when testing
UASP gadget with dwc3 driver.

usb: gadget: defer setting maxpacket till ->setup()
maxpacket is set by the udc driver for ep0 very early. This value is
copied by the function gadget used later for the USB_DT_DEVICE and
USB_DT_DEVICE_QUALIFIER query. This seems to work fine so far. For USB3
we need set a different value here. In SS speed it is 2^x with x=9 and
in HS we set something <= 64. If the UDC starts in SS and continues in
HS after the cable has been plugged it will report a too small value.
There setting of this value is defered and taken automaticly from the
ep0 pointer where the UDC driver can update it according to the speed it
detected _after_ a cable has been plugged.

usb: gadget: add max_speed to usb_composite_driver
This field is used by the Gadget drivers to specify
the maximum speed they support, meaning: the maximum
speed they can provide descriptors for.
The driver speed will be set in consideration of this
value.

usb: gadget: add streams support to the gadget framework
This patch defines necessary fields to support
streaming for USB3.0.
It implements a new function, called
usb_ep_autoconfig_ss(), to be used instead of the
existing usb_ep_autoconfig() when working in
SuperSpeed mode and there is a need to search for
an endpoint according to the number of required
streams.

[idos@codeaurora.org: Changed also the following files to
comply with this commit: f_accessory.c,f_adb.c,f_diag.c,f_mtp.c,
f_rmnet.c,f_rmnet_sdio,f_rmnet_smd,f_rmnet_smd_sdio,f_serial.f_ccid.c.
Also merged a patch in f_serial.c for correct checking of the return value
of config_ep_by_speed. See "usb: gadget: fix g_serial regression".
Also fix a bug in ci13xxx_udc. Since f_serial is now checking if the endpoint
descriptors are null in the set_alt function, need to set them to null on
ep_disable in case of cable disconnect. Since the ep descriptor was inserted
to struct usb_ep in "usb: gadget: add usb_endpoint_descriptor to struct usb_ep"
then simply convert the ci13xxx_udc to work with mEp->ep.desc instead of
mEp->desc, this will ensure that the correct descriptor will be cleared
on endpoint disable.
I will upstream it to Linux community soon, I will name it:
"usb: gadget: use usb ep descriptor of struct usb_ep instead of wrapper desc"]

usb: gadget: add usb_endpoint_descriptor to struct usb_ep
Change usb_ep_enable() prototype to use endpoint
descriptor from usb_ep.
This optimization spares the FDs from saving the
endpoint chosen descriptor. This optimization is
not full though. To fully exploit this change, one
needs to update all the UDCs as well since in the
current implementation each of them saves the
endpoint descriptor in it's internal (and extended)
endpoint structure.

usb: gadget: convert all users to the new udc infrastructure
peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
register/unregister to the udc-core.
The udc-core will take the first available gadget driver and attach
function driver which is calling usb_gadget_register_driver(). This is
the same behaviour we have right now.
Only dummy_hcd was tested, the others were compiled tested.

commit b657342882
Author: Felipe Balbi <balbi@ti.com>
Date: Tue Jun 28 16:33:46 2011 +0300
usb: gadget: introduce UDC Class
this class will be used to abstract away several of the duplicated
operations scattered among the USB gadget controller drivers.
Later, we can add an atomic notifier to tell interested drivers about
what's happening with the controller. Notifications such as suspend,
resume, enumerated, etc. will be useful, at a minimum, for implementing
usb charger detection.
As part of the converting process usb_gadget_probe_driver() is no longer
part of each udc but pushed into the ->stap() callback. The same for his
couterpart.
The core is currently set explicit to 'n'. It will be changed to 'y' once
all users are converted since it provides functions which clash with
other drivers.

usb: dwc3: gadget: driver should not wait for RxFIFO to drain
An older version of the databook said to wait for the FIFO to
drain, but that has been removed from the newer databooks.
Waiting for RxFIFO to drain caused problems when testing against
one of the host controllers available in the market.
After talking to one of the RTL engineers, he stated that we
should _not_ wait for RxFIFO to drain.

usb: dwc3: gadget: replace mdelay with udelay in the busy loop
There are two spots where we wait until the HW finishes processing a
certain command. Initially we had a few problems and we used 500ms as a
limit to be on a the safe side. Paul Zimmerman mentioned this is little too
much. After a debugging session, we noticed that we hardly ever go over 20us
and didn't pass 30usec so far. Using mdelay() seems way overloaded.
Giving the current numbers 500usec as the upper limit is more than enough.
Should it ever timeout then something is definitely wrong.
While here, also replace the type with u32 since long does not really
fit here.

usb: dwc3: gadget: rework the dequeue on RESET & DISCONNECT
- since a while we are disabling an endpoint and purging every requests on
RESET and DISCONNECT which leads to a warning since the endpoint was
disabled twice (once by the UDC, and second time by the gadget). I
think UDC should nuke all requests because all those requests
become invalid. It's gadget driver's responsability, though, to disable
its used endpoints. This is done by merging dwc3_stop_active_transfer()
and dwc3_gadget_nuke_reqs() into dwc3_remove_requests().
- dwc3_stop_active_transfer() is now no longer called unconditionaly.
This has the advantage that it is always called to disable an active
transfer which means if res_trans_idx 0 than something went wrong and
it is an error condition because we can't clean up the requests.
- Remove the DWC3_EP_WILL_SHUTDOWN which was introduced while
introducing the command complete part for dequeue. All requests on
req_queued list should be removed during the dwc3_cleanup_done_reqs()
callback so there is no reason to go through the list again.
We consider it an error condition if requests are still on this
list since we never queue TRB without LST=1 (the last requests has
always LST=1, there are no requests with LST=0 behind it).

There are some issues around for enabling/disabling this mode and

So I'm for removing it and bringing a working version back once there is
a need for it.

usb: dwc3: ep0: simplify EP0 state machine
The DesignWare USB3 core tells us which phase
of a control transfer should be started, it
also tells us which physical endpoint needs
that transfer.
With these two informations, we have all we
need to simply EP0 handling quite a lot and
get rid rid of the SW state machine tracking
ep0 states.
For achieving this perfectly, we needed to
add support for situations where we get
XferNotReady while endpoint is still busy
and XferNotReady while gadget driver still
hasn't queued a request.

usb: dwc3: ep0: add handling for unaligned OUT transfers
In case we have transfers which aren't aligned
to wMaxPacketSize, we need to be careful with
how we start the transfer with the HW. OUT
transfers _must_ be aligned with wMaxPacketSize
and in order to guarantee that, we use a bounce
buffer.

usb: dwc3: add a bounce buffer for control endpoints
This core cannot handle OUT transfers which aren't
aligned to wMaxPacketSize, but that can happen at
least on control endpoint with the USB Audio Class.
This patch adds a bounce buffer to be used on the
case of a non-aligned ep0out request is queued.

usb: dwc3: Introduce DesignWare USB3 DRD Driver
The DesignWare USB3 is a highly
configurable IP Core which can be
instantiated as Dual-Role Device (DRD),
Peripheral Only and Host Only (XHCI)
configurations.
Several other parameters can be configured
like amount of FIFO space, amount of TX and
RX endpoints, amount of Host Interrupters,
etc.
The current driver has been validated with
a virtual model of version 1.73a of that core
and with an FPGA burned with version 1.83a
of the DRD core. We have support for PCIe
bus, which is used on FPGA prototyping, and
for the OMAP5, more adaptation (or glue)
layers can be easily added and the driver
is half prepared to handle any possible
configuration the HW engineer has chosen
considering we have the information on
one of the GHWPARAMS registers to do
runtime checking of certain features.
More runtime checks can, and should, be added
in order to make this driver even more flexible
with regards to number of endpoints, FIFO sizes,
transfer types, etc.
While this supports only the device side, for
now, we will add support for Host side (xHCI -
see the updated series Sebastian has sent [1])
and OTG after we have it all stabilized.

Also fix a bug in ci13xxx_udc. Since f_serial is now checking if the endpoint
descriptors are null in the set_alt function, need to set them to null on
ep_disable in case of cable disconnect. Since the ep descriptor was inserted
to struct usb_ep in "usb: gadget: add usb_endpoint_descriptor to struct usb_ep"
then simply convert the ci13xxx_udc to work with mEp->ep.desc instead of
mEp->desc, this will ensure that the correct descriptor will be cleared

Later, we can add an atomic notifier to tell interested drivers about
what's happening with the controller. Notifications such as suspend,
resume, enumerated, etc. will be useful, at a minimum, for implementing
usb charger detection.
As part of the converting process usb_gadget_probe_driver() is no longer

commit 18b7ede5f7ee2092aedcb578d3ac30bd5d4fc23c upstream.
[ removed the dwc3 portion of the patch as it didn't apply to
older kernels - gregkh]
According to USB 3.0 Specification Table 9-22, if
bmAttributes [4:0] are set to zero, it means "no
streams supported", but the way this helper was
defined on Linux, we will *always* have one stream
which might cause several problems.
For example on DWC3, we would tell the controller
endpoint has streams enabled and yet start transfers
with Stream ID set to 0, which would goof up the host
side.
While doing that, convert the macro to an inline
function due to the different checks we now need.
