Remove the use of global variable from ITE tech touch driver,
and use the internal driver structure passed as function argument.
This change makes the driver complied to kernel coding standards
and similar to other touch driver.
This is a propagated patch from 3.18 patch 'commit 041f90ddeb5e ("input:
touchscreen: remove global variable from ITE tech touch driver")'

Identify the ITE tech controller until it is ready to do any
i2c transaction. This is needed for dynamic detection and to check
if ITE tech controller is connected or not.

Don't allow ITE tech driver to check the status of the controller forever
before any i2c read/write, instead make it to 10 times only.
In case of firmware flashing and external calibration features, this is
made to 500 times.

'commit 5e8c98c6705b ("input: touchscreen: don't allow ITE tech driver
to do infinite i2c checks")'

Before doing any i2c read/write, driver needs to check the value
of QUERY buffer to know if the controller is in ready or busy state.
Sometime, it takes more number of checks to know the status.
So this change increases the number of checks to know the ITE tech
touch controller status.

touchscreen: increase number of checks for touch controller status")

During playback, enabling smart boost feature changes the threshold
of the playback signal based on the amplitude of the signal without
clipping the signal. Change enables smart boost on WCD9340 codec.

WCD9335 codec has single master clock supply widget for both
playback and recording paths. Adding separate clock supply
for playback and recording paths will help handle low power
audio recording usecases without affecting playback usecases.
Change is to enable separate clock supply widgets for playback
and recording paths.
