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.
This is a propagated patch from 3.18 kernel 'commit 60589278b8e7 ("input:
touchscreen: increase number of checks for touch controller status")

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
This patch is propagated from 3.18 kernel
'commit 091a01709e12 ("input: msg21xx_ts: update mstar
driver to enable msg2138A")'

- Comparisons should place the constant on the right side of the test
- struct of_device_id should normally be const

Device crash is observed for consecutive SSR's triggered during WFD
playback. This is due to callback functions registered by afe client
aren't reset during the first SSR and the same callback functions are
being used for the next SSR event, resulting access in freed data.
Fix this issue by resetting the callback functions during SSR.

When display is turned off, ensure that the lcd mode selection GPIO is
set to output LOW. This would prevent any current leakage from that GPIO
whenever display is off.

Introduce a flag to know if modem is restarting from cold boot or from
SSR.
Use this flag to decide if modem memory needs to be assigned back to
linux. After cold boot linux already owns modem memory and trying to
assign it back from modem is incorrect.

Decoder YUV buffer size should be derived based on current
resolution using Venus MACROS. This the only size that
clients are aware of. Using the size from FW will make
buffer sizes mismatches and unnecessary failures.
By not using buffer size from Venus, driver can avoid
unnecessary buffer requirement calls. This will reduce the
start-up latency.
