2.34.1
From: ChiYuan Huang <[email protected]>
For E1 sample, there's the current bias issue. Some undocumented RGs
should be runtime controlled during the DAPM flow to prevent the
abnormal false alarm protection latchup.

Hi,
Our E1 sample is evaluated by some end customer. Alghouth it's not the
final MP version. But to be compatible with the engineering sample, this
fix can solve the amp on issue.
