- During bootup, create a file system storing the
information about usb device state and name, and
broadcast the message to userspace whenever the
device is plugged or unplugged.
- Register the device at USB sound card initialization
for creating file system and toggle the state in that
filesystem when USB is plugged/unplugged. This will
also send a message to user space informing it about
state change.

mmcq performance numbers are not captured since asynchronous

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"

mmc_set_ios() is used by host drivers during suspend/resume
routines in indirect way i.e., by calling host->ops->set_ios().
But now with MMC_CLKGATE enabled, mmc_set_ios() also updates
host->clk_gated flag. So export this API so that host controller
drivers can use it.

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.

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.

Qualcomm SDCC controller supports minimum SD clock frequency
which is required for card initialization. This information is
exported through platform data for each SDCC controller. There is
no need of retrying higher frequencies than the minimum supported
by controller for Qualcomm chipsets which inturn add delay in
detection process if there is no card during suspend/resume cycles.
Hence, skip multiple frequency retries.

When SD/MMC card is removed without unmounting and
then reinserted again while gendisk is freed. Partition
invalidation and deletion may take more than 10secs during
which SDCC controller can suspend due to runtime pm functionality.
Once the block layer activity is done it claims host to detach card
from MMC bus which triggers SDCC resume. As the host->card is
NULL already there is a BUG_ON hit in mmc_sd_resume(). Fix this
by claiming host even before we free host->card.

MMC core reads SEC_COUNT information from EXT_CSD register and assumes
that the card supports sector access mode. Some eMMC cards (<=2GB) do not
support this mode even though they have SEC_COUNT value defined, causing
failure while populating extended partitions. Sector/Byte access mode
information is stored in OCR register. Hence, read OCR bit 30 and then
confirm it with SEC_COUNT value to know whether the card supports sector
access mode or byte access mode.

For the Nand controller on 7x30 and 7x27a, the
uncorrectable error bit in the NANDC_BUFFER_STATUS
register is changed to BIT(8) from BIT(3) (in legacy
targets) due to change in the ECC requirements. Currently,
this is handled only in dual nandc mode (default for 7x30
and 7x27a). In case, if only single nandc is used, the
uncorrectable bit check is broken and the driver wouldn't
detect any ECC errors.
Add software version info in platform data to differentiate
between the targets that have different register interface.
