HDMI-Audio: Fix Spinlock-Recursion and Null-Pointer issues

BZ: 21688 37320

Change to prevent Recursive spinlock in trigger.
In middle of start trigger, if HDMI is Pluged-out, the driver
state is disconnected and unplug function calls snd_pcm_stop to
inform the upper layer about disconnection. This internally calls
snd_pcm_stop and stop trigger. Here the lock is recursively
acquired. Solution is to not call snd_pcm_stop if the
substream is active.

Change to prevent Substream NULL during programming buffer.
During successive quick plug and unplug of HDMI cable,
unplug is processed before Start trigger gets to process.
But the trigger state is saved. On unplug the Stop trigger is
called and because it is disconnected it does nothing. Once
cable is plugged in silence is played and the old saved
start trigger causes to retrieve the substream which is NULL
at this point of time. Solution is to clear Trigger state during
unplug. During Plugin inform the upper layer about the event,
if the substream is still active.

HDMI Audio code ported from R2 branch contains Dummy_playback
code. This workaround is no longer needed in R3. (ICS platform)
This patch removes dummy_playback implemtation. Some variables
are renamed for better readability.

clocal = 0 : Wait for Carrier Detect from modem

sfi-cpufreq : Modifying residency_count_multiplier according to maximum operating frequency supported by the platform

BZ: 38418

P-state driver calculates the CPU load value based upon the C-state(C2 to C6)
residencies in the given time interval. Since MSRs record the residency with 1MHz clock,
to compute the actual residency at maximum speed, the value should be multiplied by
a factor = (maximum clock / 1M ).

This patch makes the calculation of this multiplier generic by taking the maximum
frequency from the frequency table as the multiplier value.

Gfx-Display: postpone hdmi encoder restore

BZ: 38178

after late resume, both mipi and hdmi are enabled, and lock screen should be
displayed. while actually an intermediate picture is showed before showing lock
screen. the reason is there is a early_suspend callback for fb device, a thread
loop in framework check its status to see whether fb device is ready to draw.
its level is 100, but the level of gfx_early_suspend is 150. so in early
suspend, the sequence is stop_drawing_early_suspend() --> gfx_early_suspend(),
while in late_resume, the sequence is gfx_late_resume() -->
start_drawing_late_resume(). so the first flip happens after enable pipe and
plane.

the solution is:
1. for mipi, before enabling pipe and plane, restore a black framebuffer.
2. for hdmi, postpone enable hdmi plane to let flip happen fist.

in term of power consumption in the case where the wakeup from deep sleep
is triggered periodically.

Actually the suspend process starts by waken up all the devices in order
to well prepare them for a deep sleep. Experimental results shows that,
depending on the devices presents on the system, the suspend increases
significantly the power if the wakeup capable alarms are configured to be
triggered before a certain threshold.

Be careful while setting this parameter: a wrong value may increase the
power consumption. So, if no full study was performed on the target
platform, please leave it at its default value.

atmel_mxt_ts: turn off anti-calibration

BZ: 38574

It is suggested from vendor to turn off anti-calibration to improve
water immunity and palm detection.

But we can't just turned off anti-calibration totally.
f.e if we put one finger on touch panel when screen is turning on,
the area under finger will not work anymore until we press power button
to turn off and on the screen to let touch do a calibration to recover.

After screen on, using a timer to wait for 10s before turning off
anti-calibration. This will give touch firmware to recover from the
above situation.

With continously insert/remove a SD card on Tablet, Fabric error

As original design, when there happens error during sending command

state. This patch will change this. If there error is NOMEDIA, means

BZ: 36939

Issue:
Board screen display flash while pressing power key to resume system on Lexington DUT.

Solution:
Case1:
When panel and interface are initializing, there maybe some noise showed on display,
We'd better turn on the backlight after the initialization operation, this can avoid some
noise issue. And it's not good turn on backlight with full brightness at the beginning,
it will cause a flash when screen on, the brightness level should be controlled by
lastbrightnesslevel parameter after initialization.
Case2:
__dpi_panel_power_on() will reset the panel and then enable DSI
PLL, config the DSI controller, then exit ULPS state, set low
power output hold, then call p_funcs->drv_ic_init(), at this
moment, the MIPI is in low power mode, so change the hs to lp in

a HEADSET if the GPIO pin says that there is a headset.
