Subject[PATCH 0/3] ASOC: cs42l42: Add support for system suspend
Date
Add system suspend and resume handlers so that the cs42l42 is cleanly
put into power-off state during system suspend and the registers are
restored in resume.

The first two patches separate out two small changes that can stand
alone and are needed to enable the system suspend implementation:

1) Don't rely on there being a jack unplug IRQ before a plug IRQ.
There won't be if the unplug and plug happened while in system suspend.

2) Put a mutex around the entire IRQ handling so that the suspend can
ensure the last run of the IRQ handler has completed before it powers
down.

Richard Fitzgerald (3):
ASoC: cs42l42: Report full jack status when plug is detected
ASoC: cs42l42: Change jack_detect_mutex to a lock of all IRQ handling
ASoC: cs42l42: Handle system suspend
