- qcom,chipid: If it exists this property is used to replace
the chip identification read from the GPU hardware.
This is used to override faulty hardware readings.
- qcom,gpu-model: If it exists this property is used for GPU model name.
- qcom,disable-wake-on-touch: Boolean. Disables the GPU power up on a touch input event.
