30edcea08f mmc: core: fix power class selection
mmc_select_powerclass() function returns error if eMMC
VDD level supported by host is between 2.7v to 3.2v.

According to eMMC specification, valid voltage for high
voltage cards is 2.7v to 3.6v. This patch ensures that
2.7v to 3.6v VDD range is treated as valid range.

Also, failure to set the power class shouldn't be treated
as fatal error because even if setting the power class
fails, card can still work in default power class.
If mmc_select_powerclass() returns error, just print
the warning message and go ahead with rest of the card
initialization.

6e611f2b86 Revert "mmc: sdio: optimized SDIO IRQ handling for single irq"
This reverts commit 06e8935feb.
With the optimization, the sdio_irq_thread() sends a spurious
interrupt notification to the registered function handler during
ksdioirq thread start up. The function handler may or may not
handle this interrupt gracefully. The correct way to inform
about interrupt is to check CCCR_INTx register for pending
interrupts before calling function driver's irq handler
which is broken with this optimization, hence the revert.

commit 1f8c5cecfe
Author: Heiko Stuebner <heiko@sntech.de>
Date:   Wed Feb 1 10:33:01 2012 -0800

    Input: evdev - fix variable initialisation

    Commit 509f87c5f564 (evdev - do not block waiting for an event if
    fd
    is nonblock) created a code path were it was possible to use retval
    uninitialized.

    This could lead to the xorg evdev input driver getting corrupt data
    and refusing to work with log messages like
    	AUO-Pixcir touchscreen: Read error: Success
    	sg060_keys: Read error: Success
    	AUO-Pixcir touchscreen: Read error: Success
    	sg060_keys: Read error: Success
    (for drivers auo-pixcir-ts and gpio-keys).

commit 4dc43d7079
Author: Arve Hjønnevåg <arve@android.com>
Date:   Fri Oct 17 15:20:55 2008 -0700

    Input: evdev - Add ioctl to block suspend while event queue is not empty.

    Add an ioctl, EVIOCSSUSPENDBLOCK, to enable a wakelock that will block
    suspend while the event queue is not empty. This allows userspace code to
    process input events while the device appears to be asleep.

    The current code holds the wakelock for up 5 seconds for every input
    device and client. This can prevent suspend if sensor with a high data
    rate is active, even when that sensor is not capable of waking the
    device once it is suspended.

    Input: evdev - Don't hold wakelock when no data is available to user-space

    If there is no SYN_REPORT event in the buffer the buffer data is invisible
    to user-space. The wakelock should not be held in this case.

commit 09701e3edf
Author: Scott Anderson <saa@google.com>
Date:   Wed Jan 18 15:56:51 2012 -0800

    usb: gadget: android: Honor CONFIG_USB_GADGET_VBUS_DRAW

    The maximum current draw was hard coded to 500 mA.  composite.c
    has code that uses CONFIG_USB_GADGET_VBUS_DRAW to set the
    bMaxPower and to set whether or not the device is self-powered if

    usb: gadget: Fix usb string id allocation

    Don't reset next_string_id every time the gadget is enabled, this makes
    the next strings allocated overwrite strings allocated at probe time.
    Instead, fix rndis not to allocate new string ids on every config bind.

    Add a comment pointing out the use of enum station_info_flags for
    all new struct station_info fields. In addition, memset the sinfo
    buffer to zero before use on all paths in the current tree to avoid
    leaving uninitialized pointers in the data.

    rtc: Fix some bugs that allowed accumulating time drift in suspend/resume

    The current code checks if abs(delta_delta.tv_sec) is greater or
    equal to two before it discards the old delta value, but this can
    trigger at close to -1 seconds since -1.000000001 seconds is stored
    as tv_sec -2 and tv_nsec 999999999 in a normalized timespec.

    rtc_resume had an early return check if the rtc value had not changed
    since rtc_suspend. This effectivly stops time for the duration of the
    short sleep. Check if sleep_time is positive after all the adjustments
    have been applied instead since this allows the old_system adjustment
    in rtc_suspend to have an effect even for short sleep cycles.

    rtc: Avoid accumulating time drift in suspend/resume

    Because the RTC interface is only a second granular interface,
    each time we read from the RTC for suspend/resume, we introduce a
    half second (on average) of error.

    In order to avoid this error accumulating as the system is suspended
    over and over, this patch measures the time delta between the RTC
    and the system CLOCK_REALTIME.

    If the delta is less then 2 seconds from the last suspend, we compensate
    by using the previous time delta (keeping it close). If it is larger
    then 2 seconds, we assume the clock was set or has been changed, so we
    do no correction and update the delta.

    Note: If NTP is running, ths could seem to "fight" with the NTP corrected
    time, where as if the system time was off by 1 second, and NTP slewed the
    value in, a suspend/resume cycle could undo this correction, by trying to
    restore the previous offset from the RTC. However, without this patch,
    since each read could cause almost a full second worth of error, its
    possible to get almost 2 seconds of error just from the suspend/resume
    cycle alone, so this about equal to any offset added by the compensation.

    Further on systems that suspend/resume frequently, this should keep time
    closer then NTP could compensate for if the errors were allowed to
    accumulate.

    Credits to Arve Hjønnevåg for suggesting this solution.

    This patch also improves some of the variable names and adds more clear
    comments.

b30c982b23 mmc: msm_sdcc: data CRC errors are expected during HS200 tuning
HS200 bus speed mode requires DLL (Delay locked loop) HW block
to be tuned as clock rate (192 MHz) is greater than 100MHz.
While tuning the DLL block by sending CMD21 for different DLL
phases, it is quite possible that few CMD21 may fail with data
CRC errors as clock phase is not correct but these errors are not
really worth to be printed out as kernel messages. This change
doesn't allow these errors to be printed.

1de2dfd13d mmc: core: capture performance numbers only when asked
Currently performance numbers are captured for each SDCC
transfers unconditionally which may add the overhead and
could reduce the SDCC read/write throughput numbers.

This change adds additional control for enabling/disabling the
capturing of performance numbers at runtime. We already have sysfs
entry named "perf" for msm sdcc devices. Currently setting this
entry to 0 clears the performance statistics. But now we are
changing the definition of this entry as mentioned below:

Disable performance capturing and clear the performance statistics:
	"echo 0 > /sys/devices/platform/msm_sdcc.<n>/perf"

Enable performance capturing:
	"echo 1 > /sys/devices/platform/msm_sdcc.<n>/perf"

dd43295060 mmc: msm_sdcc: don't call udelay() from msmsdcc_delay()
With SDCC4, driver can check the register synchronization
by polling REG_WR_ACTIVE bit in MCI_STATUS2 register so in
that case there is no need to ensure register synchronize
using explicit delay (achieved by calling udelay()).

But there are many places in driver which calls the msmsdcc_delay()
to achieve atleast 1us delay. So this patch have identified such
places and changed them to call a function which guarantees
to have atleast 1us of blocking delay.

187022181f msm: msm_sdcc: defer device resume until next transfer request comes
If SDCC device runtime status was RPM_RESUMED before system suspend
happens, during next system resume SDCC will also be resumed
synchronously. As SDCC resume is happening as part of system resume
path and it may take around 150ms to resume for SDCC slot which have
SD card connected. As this resume latency is too high, it may impact
overall system resume time and can effect the user experience.

This change makes sure that during system suspend, device runtime
status gets set to RPM_SUSPENDED. So when system resume happens,
SDCC resume can be skipped which means SDCC resume is deferred
until next SDCC transfer request comes in.

1. SDCC driver resume gets called which does nothing as it will
   find the device as runtime suspended.
2. As part of dpm_resume() itself, mmc_bus_resume() is called which
   results in this call flow:
	mmc_bus_resume -> mmc_blk_resume -> mmc_blk_set_blksize ->
	mmc_claim_host -> mmc_host_enable -> host_ops->enable ->
	SDCC driver runtime resume.

We really don't want to do runtime resume of SDCC as part of
dpm_resume() othewise it will increase the latency of overall
system resume path.

For sector addressed cards (card size > 2GB), default blocksize is
512 bytes which means setting block length by sending
CMD16 (SET_BLOCKLEN) is not required for such cards. But
mmc_blk_set_blksize() first claims host and then check if card requires
CMD16 or not. mmc_claim_host() will cause runtime resume of SDCC device.
So it's better to first check if card requires CMD16 or not for setting
block length to 512 and then claim the host only if it's required.

f4a999cf00 mmc: msm_sdcc: fixup for enabling MMC_CLKGATE feature for SDIO cards
In the current implementation, turning off SDCC clocks when
SDIO card is inserted, is controlled by the SDCC driver in
suspend/resume callbacks. This makes the dynamic clock gating
(MMC_CLKGATE) feature, when enabled, to be broken for SDIO cards,
as configuring of sdio wakeup interrupt is entirely handled
in system suspend/resume callbacks. Handle this by moving all
of the wakeup handling code to generic set_ios function which can be
called either from core layer or driver layer.

Since the SDCC controller supports asynchronous notification of
SDIO card activity when the clocks are off use this for enabling
MMC_CLKGATE feature which helps in TCX0 during idle state.

Also, handle the case where the SDIO function driver is not interested
in waking up the system during suspend but the SDCC driver still
configures DAT1 line as wakeup interrupt.

4dd5c44e48 mmc: sd: fix the issue with paranoid SD card init retry
mmc_resume_host() is called during resume (runtime or system) which calls
	1. mmc_power_up
	2. mmc_select_voltage
	3. host->bus_ops->resume() (mmc_sd_resume())

mmc_sd_resume() ultimately calls mmc_sd_init_card() to initialize the
SD card. But let's say if mmc_sd_init_card() fails during the
execute_tuning(). At this point, host controller timing is changed
to SDR104/SDR50 mode and host clock will also be > 100 MHz.

If there is an error returned by mmc_sd_init_card() and
if CONFIG_MMC_PARANOID_SD_INIT defined, it retries by calling
mmc_sd_init_card() without making sure that host controller timing
and clock be initialized again. This may cause the further
mmc_sd_init_card() also to fail.

To fix this, mmc_sd_resume() should call mmc_power_up()
and mmc_select_voltage() before retrying.

ed6b0e409c mmc: msm_sdcc: reset wait_for_auto_prog_done flag in case of an error
"wait_for_auto_prog_done" flag is set when CMD53, single block write
(CMD24) or pre-defined (prefixed with CMD23) multi block write
(CMD25) need to be sent to card. This flag tells the
msmsdcc_start_data() to set the AUTO_PROG_DONE bit in MCI_DATA_CTL
register. If AUTO_PROG_DONE bit is set, SDCC controller will raise
the PROG_DONE at the end of above mentioned write transfers
(command + data) and "wait_for_auto_prog_done" gets cleared at
the end of transfer.

But if we get the error during the command transfer phase itself,
there is a chance that "wait_for_auto_prog_done" remains set which
means it remains sticky during next SDCC transfer request as well.
And if next data transfer is data read operation, having this
"wait_for_auto_prog_done" flag set will not allow the transfer to
end which may cause SDCC driver to raise request timeout.

Following is one such error condition:
<6>[  667.001892] mmc1: CMD6: Request timeout
<6>[  667.004700] mmc1: SDCC PWR is ON
<6>[  667.007904] mmc1: SDCC clks are ON, MCLK rate=400000
<6>[  667.012848] mmc1: SDCC irq is enabled
<6>[  667.067633] mmc1: SPS mode: busy=0
<6>[  667.071020] mmc1: xfer_size=64, data_xfered=64, xfer_remain=0
<6>[  667.076758] mmc1: got_dataend=1, prog_enable=0,
			wait_for_auto_prog_done=1, got_auto_prog_done=0

This patch ensures that "wait_for_auto_prog_done" gets cleared even when
error is seen during command transfer phase itself.

enable HS200 timing in device.

2. After the device is set to HS200 mode, the host driver
must send tuning command CMD21 to find the optimal sampling
point for data lines.

3. Depending on the voltage range and HS200 modes supported
by the host and device, host driver must change the voltage
range of VccQ whenever the MMC core driver requests it.

4. Change the controller timing mode and MCLK frequency to
maximum frequency supported by host.

9d3eeff5f2 mmc: core: hs200 fixes
This patch fixes following issues when HS200 is enabled:

1. If executing_tuning() host ops is called without mmc_host_clk_hold(),
   card clocks might get turned off (if MMC_CLK_GATING is enabled)
   while execute_tuning() is in progress. So this patch makes sure
   that execute_tuning() is called with mmc_host_clk_hold().

2. If host timing mode is set to HS200 mode, there should not be
   any communication with the card until execute_tuning() is completed.
   But there is a chance that CMD6 might be sent to enable set HPI_EN
   (of HPI_MGMT field in EXT_CSD) before execute_tuning() is called.
   So this patch moves this operation after execute_tuning() is completed.

ecfa3df471 mmc: msm_sdcc: Fix scatterlist processing in PIO mode
sg_miter_next() does not place byte alignment restrictions on
sgl lengths. However, SDCC FIFO must be accessed in multiples
of 4 bytes, requiring rounding which can cause data corruption.

For example, an sgl of length 481 is decribed below:
	struct scatterlist sgl;
	sgl.page_link = 0xXXXX_XXXX;
	sgl.length    = 481;
	sgl.offset    = 3821;

First call to sg_miter_next():
	Sgl length returned = (PAGE_SIZE - 3821) = 275 bytes
	Driver rounds this length to multiple of 4 = 276 bytes

Next call to sg_miter_next():
	Sgl length returned = (481 - 275) = 206 bytes
	Driver rounds this length to 208 bytes

On a write, the extra byte written to the FIFO during the first
276 byte chunk is assumed valid. The next call writes 208 bytes,
but the last 3 bytes (276 + 208 - 481) including 1 valid byte,
are ignored, as the controller uses the MCI_DATA_LENGTH register
to figure out that it only needs to write a total of 481 bytes.

To fix the data corruption in cases as above, a 4 byte bounce
buffer is used realign buffer access to the FIFO, such that 4 byte
multiples are written until the last buffer chunk.

Note that in a simple case where all 481 bytes lie within a page,
the driver rounds the length to 484, but the MCI_DATA_LENGTH
register enusres only 481 bytes are actually written.

switch from 3.3v to 1.8v is not required.

0007bbcad4 mmc: core: Add default timeout value for CMD6
EXT_CSD[248] includes the default maximum timeout for CMD6.
This field is added at eMMC4.5 Spec. And it can be used for default
timeout except for some operations which don't define the timeout
(i.e. background operation, sanitize, flush cache) in eMMC4.5 Spec.

b5716b4be2 mmc: core: move ->request() call from atomic context
mmc_request_done() is sometimes called from interrupt or other atomic
context.  Mostly all mmc_request_done() does is complete(), however it
contains code to retry on error, which uses ->request().  As the error
path is certainly not performance critical, this may be moved to the
waiting function mmc_wait_for_req_done().

This allows ->request() to use runtime PM get_sync() and guarantee it
is never in an atomic context.

8fe21151ad mmc: core: ext_csd.raw_* used in comparison but never set
f39b2dd9d ("mmc: core: Bus width testing needs to handle suspend/resume")
added code to only compare read-only ext_csd fields in bus width testing
code, yet it's comparing some fields that are never set.

The affected fields are ext_csd.raw_erased_mem_count and
ext_csd.raw_partition_support.

4495671c37 mmc: block: fix boot partition switch error path
In the case of a switch error, do not update partition config as though
the switch succeeded, and ensure blk_end_request is called on the
failed request.
