Subject: [PATCH 257/464] ASoC: sun50i-codec-analog: Move suspend/resume to
|
||
|
|
set_bias_level
|
||
|
|
|
||
|
|
With idle_bias_on and suspend_bias_off, there are bias level transitions
|
||
|
|
that match the suspend/resume callbacks. However, there are also
|
||
|
|
transitions during probe (OFF => STANDBY) and removal (STANDBY => OFF).
|
||
|
|
|
||
|
|
By using the set_bias_level hook, the driver can have one copy of code
|
||
|
|
that would otherwise be duplicated between the probe/resume and
|
||
|
|
suspend/remove hooks.
