FM configuration failure is due to two issues. Since the calibration
will take around 6 seconds to complete, any commands sent to SOC
during that time will fail.Added a state machine to prevent the
execution of another command while FM calibration is in progress.
The other issues is with the Get tuner command.FM kernel driver is
sending the Rx specific command to get the Tx configuration.
Send the proper command to get the TX configuration parameters.

Because the IBs used for context switching are not allocated
by userspace, a separate search is needed to find them
in adreno_find_region.

Some hangs are fooling the postmortem dump code into
running off the end of a buffer. Fix this by making
its bounds check logic work better by reusing the
logic from kgsl_find_region().

This change disables all the HDCP interrupts upon de-authentication.
In addition, we also clear the HDCP AUTH_FAIL_INFO register upon
processing the AUTH_FAIL_INT interrupt. This is required for passing
HDCP compliance for MSM8960

Delay in headset removal causes adverse effects in
userspace such as delay (loss) in audio/video routing.
Delay was introduced to reject spurious switch events. These
events are already rejected based on the headset status.

Use deferable timer in background operations thread,
so that it won't cause unnecessary wakeups. Typically,
wakeups are seen in the range 60ms to 2secs (for HZ=100)
after the thread is scheduled out. In general, during this
delay the processor can go into sleep, if there is no other
activity. Since, the work done in this background operation
is not critical and can be handled as soon as when timer
expires and processor wakes up for other critical events,
we mark the timer responsible for wakeup of this thread
as deferable timer. Otherwise, the processor wakesup
unnecessarily to handle the background operations causing
higher power consumption in idle state.

Add two APIs, 1) set_current_limit API and 2) set_charging_by.
set_current_limit api is used for external control, such as for USB
driver to tell a charger driver the maximum current to draw.
set_charging_by is used to change the state of the charger.

When mmap is called to remove a mapping, the mmap code
takes care of removing all the entries so it isn't
necessary to call unmap versions. However, there may be
cases where heaps need to do other buffer clean up when
a userspace buffer is unmapped. Add an unmap_user function
to the ion heap ops. This callback needs to happen in
vma_close, so move the decrementing of the overall user map
call back as well.

Ion allows multiple mmaps of the same buffers. This means that
incrementing the usermap count in mmap and decrementing it in
release is not sufficient as release will only ever be called
once. Fix this by only doing the reference count change in the
vma_open and close which are called whenever mmap is called.

When performing cpu hotplug tests the kernel printk log buffer gets flooded
with pointless "Switched to NOHz mode..." messages. Especially when afterwards
analyzing a dump this might have removed more interesting stuff out of the
buffer.
Assuming that switching to NOHz mode simply works just remove the printk.

The HPH PA's are turned OFF while setting up MBHC hardware for
insertion detection. It is also required to turn off the DAC's for
both HPH Left and Right channels.
Turning off HPH DAC's avoids probable fake insertion interrupts.

With headset inserted and no recording, the MIC BIAS is switched to
VDDIO to avoid noise on Headphone due to button polling. When this
switch happens, it is required to pause the headset polling before
the switch and restart it again when the switch is done
This will make the MIC BIAS switch smooth and will avoid click/pop
noise that may happen during the switch

When the headset is inserted more than three quarter inside, the tip
of headset plug just touches the HPH Left line on Headset jack. This
causes an interrupt, but is identified as fake insertion interrupt,
since the headset is still not completely inserted and the microphone
voltage has not settled. This happens continously because after detecting
fake insert, the current logic re-enables insertion detection interrupt.
Once the fake insert interrupt is triggered, the HPH left schmitt trigger
is turned OFF and the MIC line schmitt trigger is turned ON. Hence the
continous interrupts do not occur anymore. Further detection happens
based on MIC line schmitt trigger until the headset is either
completely inserted or completely removed.
