here the clock is an internal clock in the internal codec. the external clock of audio controller is managed in system suspend/resume as you see. but they are not managed in runtime suspend/resume here because the external clock is always enabled to make sure the charge pump to be working to make the board have stable current and voltage. otherwise, touchscreen ADC will not be accurate.
Why aren't these drivers keeping the clock enabled themselves?
