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.

    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
    they haven't been set.  This change removes the code in android.c
    to allow composite.c to set them.

    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.

    nl80211/cfg80211: Make addition of new sinfo fields safer

    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.

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"

Subhash Jadavani
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.

   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.

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.

1cb54eaaca mmc: core: add non-blocking mmc request function
Previously there has only been one function mmc_wait_for_req()
to start and wait for a request. This patch adds:

 * mmc_start_req() - starts a request wihtout waiting
   If there is on ongoing request wait for completion
   of that request and start the new one and return.
   Does not wait for the new command to complete.

This patch also adds new function members in struct mmc_host_ops
only called from core.c:

 * pre_req - asks the host driver to prepare for the next job
 * post_req - asks the host driver to clean up after a completed job

The intention is to use pre_req() and post_req() to do cache maintenance
while a request is active. pre_req() can be called while a request is
active to minimize latency to start next job. post_req() can be used after
the next job is started to clean up the request. This will minimize the
host driver request end latency. post_req() is typically used before
ending the block request and handing over the buffer to the block layer.

Add a host-private member in mmc_data to be used by pre_req to mark the
data. The host driver will then check this mark to see if the data is
prepared or not.

81306ad7f4 mmc: queue: let host controllers specify maximum discard timeout
Some host controllers will not operate without a hardware
timeout that is limited in value.  However large discards
require large timeouts, so there needs to be a way to
specify the maximum discard size.

A host controller driver may now specify the maximum discard
timeout possible so that max_discard_sectors can be calculated.

However, for eMMC when the High Capacity Erase Group Size
is not in use, the timeout calculation depends on clock
rate which may change.  For that case Preferred Erase Size
is used instead.

19859ef3f6 mmc: msm_sdcc: Fix deadlock in mmc_suspend_host and mmc_rescan
SDCC runtime suspend can race with mmc_rescan causing deadlock.
The call flow would be this:
1) When runtime suspend is triggered:
	msmsdcc_runtime_suspend()
		-> mmc_suspend_host()
			-> mmc_flush_scheduled_work()
2) mmc_flush_schedule_work() waits for mmc_rescan() work
to be completed if it is already in runqueue.
3) When mmc_rescan() is scheduled to run:
	mmc_claim_host()
		-> msmsdcc_enable()
			->pm_runtime_get_sync()
4) pm_runtime_get_sync() waits for runtime_suspend to complete,
and hence cause two threads to wait upon each other.

Fix this deadlock by aborting runtime suspend when mmc_rescan
is scheduled.

commit 7f7e4129c23f0419257184dff6fec89d2d5a8964 upstream.

During a rescan operation mmc_attach(sd|mmc|sdio) functions are
called. The error handling in these function can trigger a detach
of the bus, which also meant a power off. This is not notified by
the rescan operation which then continues to the next attach function.

If a power off has been done, the framework must never send any
new commands to the host driver, without first doing a new power up.
This will most likely trigger any host driver to hang.

Moving power off out of detach and instead handle power off
separately when it is actually needed, solves the issue.

0d0bc29d8c mmc: core: Use delayed work in clock gating framework
Current clock gating framework disables the MCI clock as soon as the
request is completed and enables it when a request arrives. This aggressive
clock gating framework when enabled cause following issues:

When there are back-to-back requests from the Queue layer, we unnecessarily
end up disabling and enabling the clocks between these requests since 8MCLK
clock cycles is a very short duration compared to the time delay between
back to back requests reaching the MMC layer. This overhead can effect the
overall performance depending on how long the clock enable and disable
calls take which is platform dependent. For example on some platforms we
can have clock control not on the local processor, but on a different
subsystem and the time taken to perform the clock enable/disable can add
significant overhead.

Also if the host controller driver decides to disable the host clock too
when mmc_set_ios function is called with ios.clock=0, it adds additional
delay and it is highly possible that the next request had already arrived
and unnecessarily blocked in enabling the clocks. This is seen frequently
when the processor is executing at high speeds and in multi-core platforms
thus reduces the overall throughput compared to if clock gating is
disabled.

Fix this by delaying turning off the clocks by posting request on
delayed workqueue. Also cancel the unscheduled pending work, if any,
when there is access to card.

sysfs entries are provided to tune the delay as needed with default
value set to 200ms.
