DA9053 i2c issue: Rarely the i2c interface of DA9053 hang and it can
not be recovered if not power off totally. The Dialog suggests adding
dummy write for DA9053 I2C register access, in order to decrease the failure
of DA9053 register access and possibility of i2c failure.

Set IDMAC_LOCK_EN_1 to make SDC display channels to generate
eight AXI bursts upon the assertion of the DMA request.
This change fixes the random garbage lines when showing
NV12 frames decoded by VPU with V4L2 output on
XGA@60 display's overlay framebuffer. V4L2 output uses
MEM_PP_MEM to do 180 degree rotation.
The issue can be reproduced by the following VPU unit test
on MX53 SMD platform:
/unit_tests/mxc_vpu_test.out -D
'-i /1920x1080_H264_AAC5.1ch.2.1ch_track1.h264 -f 2 -w 1024

- Move the majority of code from the IRQ handler routine into a workqueue
routine. This should improve system interrupt latency.
- Change the spin_lock protecting EPDC queues into a mutex and change all
associated spin_lock calls into mutex calls.

When setup irq is received, the status phase of the transfer is primed
on ep0 before the data phase. The usb requests are added to the list
of transfer descriptors (maintained by driver) in reverse of their
expected completion order. Completion order is data followed by status,
however the list of tds contains status followed by data.
Upon completion of the data request, the irq handler proceeds to check
the 1st td in the list -- the status request. In full speed mode,
the status phase has not yet completed at this time, so the td's
ACTIVE bit is still set. This leads irq handler to ignore the completion
interrupt without checking the actual td for the data request that caused
the interrupt.
In high speed mode, this issue does not bear itself out because the status
request also completes by the time the irq handler goes to process the data
completion interrupt.
The simple fix for this issue is to prime the status request AFTER the data
request, so that the list of tds maintained by the driver contains the tds
in the order of expected completion.

a counter used in sdhci_enable_sdio_irq function is not correct.
calling the function with enable flag will skip enabling the irq if it
follows two continuous calls with disable flag because of the counter.
to resolve this problem, simply set the counter to 1 or 0 instead of counting.

The standard EHCI design will clear RS bit after usb bus goes to
suspend, but it causes some remote wakeup issues, like remote-wakeup
featured device will be reset after resuming.
According to usb 2.0 spec, the SOF need to be sent out within 3ms
after resume signal ends, or device may consider host disconnects
with device. Freescale's USB Controller (Chipidea's core) will ends
up resume signal automatically within 21ms after it recevices remote
wakeup signal. So, if software does not set RS bit within 21ms after
it recevices remote wakeup signal, the problem described above will
be occurred.

At armv7 SoC, the dma_alloc_coherent returns non-cachable, but
bufferable region, so the driver needs to drain write buffer by
itself, if the controller needs to visit dma buffer immediately
after cpu writes
There is a discussion for this armv7 change:
http://marc.info/?t=127918539100004&r=1&w=2
For this issue, the next dtd pointer is invalid sometimes, the reason
is the region which is used to store dtd is dma buffer, so the data may
not be written to memory when the controller visit this data.

Changes Made
--------------
1) On Pen UP the TSI threads are stopped and
On Pen DOWN TSI threads are started
2) Removed TSI thread creation from Probe,
instead creating the TSI threads when PEN DOWN
Expected Output
-------------------
1) TSI threads to stop either when system is suspended or,
there is no touch event.Thus conserving power during system
suspend, idle and no touch event.
2) TSI threads to start only on touch event and not when system is resumed.
3) On system Start/Restart TSI threads will not be created and started till
the touch detection.

Asrc not works with ssi, it partly caused by ASRC driver not correctly
handle ssi input clock and data format.
SSI frame clock counting by word, when data format is 16bit-LE,
two channel data combine to one word, and frame rate used by
ASRC should take this into account.
And more, unlike Mx3x, Mx5x should set input and output data format
correctly in its ASRMCR1x register.

3) Synchronize fb unblanking operation bewteen
Android early suspend and mxcfb_set_par() to
avoid fb being unblanked after early suspend
is done, as Android early suspend doesn't
