I tried to implement HDQ protocol in device driver. When I controlled the GPIO3
on PMU, It need to be controlled by i2c. But responding time is too long to
implement HDQ protocol.

We will re-design hardware version GTA02A5. HDQ protocol is controlled by two
GPIOs. That will decrease response time while using i2c.
