			   This is used to override faulty hardware readings.

- qcom,strtstp-sleepwake:  Boolean. Enables use of GPU SLUMBER instead of SLEEP for power savings

- qcom,gx-retention:  	   Boolean. Enables use of GX rail RETENTION voltage

- qcom,disable-wake-on-touch:   Boolean. Disables the GPU power up on a touch input event.

- qcom,disable-busy-time-burst:

				Boolean. Disables the busy time burst to avoid switching

				of power level for large frames based on the busy time limit.
