I may understand your point, you suggest to use the .set_bias_level
interface. But in my case I need to enable the clock in earlier stage
and keep the clock on when system go to suspend.
I am not sure .set_bias_level can met my requirement. we start
the Chinese new year holiday now, so currently I can't do test for this
recommendation.
Maybe we can keep current implementation, can we?
Later after I do the test, I can submit another patch for it.
Best regards
