Mstar driver uses the ic-type DT property for dynamic detection
support. Driver reads a register from the controller and compares
both the values to check if connected touch controller is of
Mstar or not.
Remove all DBG messages and convert them to dev_dbg/info.
Add a debugfs entry for suspend/resume.
Remove ts_data/pdata global declaration and use dev_get_drvdata()
and input_set_drvdata()/dev_set_drvdata() instead.

Add sysfs entries to upgrade the firmware from userspace. Update_fw
sysfs entry upgrades the firmware inside the touch controller only
when the controller's firmware version is lesser than that in
userspace's firmware file. Force firmware upgrade sysfs entry
forcefully upgrades the firmware inside the touch controller even
when the controller's firmware version matches that of the firmware
file in userspace.

Mstar reference driver is being cleaned up to be checkpatch
compliant. Add Kconfig and Makefile changes to enable Mstar
driver's compilation. And following new features are added to
the driver:
1. Pinctrl support
2. Threaded irq support
3. Release all touches in suspend
4. Protocol B compliance
5. Explicit suspend/resume function
6. Configure gpios in suspend/resume function
7. Add device tree parser function
8. Add dtsi support for gpio, regulator, I2C address, display coords

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.
