extcon: axp288: Add wakeup support

2020-04-08T07:11:07+00:00

commit 9c94553099efb2ba873cbdddfd416a8a09d0e5f1 upstream.

On devices with an AXP288, we need to wakeup from suspend when a charger
is plugged in, so that we can do charger-type detection and so that the
axp288-charger driver, which listens for our extcon events, can configure
the input-current-limit accordingly.

extcon: arizona: Factor out microphone and button detection

2019-12-09T11:18:15+00:00

Continue refactoring the microphone detect handling by factoring
out the handling for microphone detection and button detection
into separate functions. This both makes the code a little clearer
and prepares for some planned future refactoring to make the state
handling in the driver more explicit.

extcon: arizona: Factor out microphone impedance into a function

2019-12-09T11:18:15+00:00

The microphone detection handler is very long, start breaking it up
by factoring out the actual reading of the impedance value into a
separate functions. Additionally, this also fixes a minor bug and
ensures that the microphone timeout will be rescheduled in all error
cases.

extcon: arizona: Invert logic of check in arizona_hpdet_do_id

2019-12-09T11:18:15+00:00

Invert the check of hpdet_acc_id at the top of arizona_hpdet_do_id to
reduce the identation within the function.

extcon: arizona: Remove excessive WARN_ON

2019-12-09T11:18:14+00:00

A WARN_ON is very strong for simply finding a button that is out of
range, downgrade this to a simple error message in the log.

extcon: arizona: Remove unnecessary sets of ACCDET_MODE

2019-12-09T11:18:14+00:00

arizona_start_mic sets ACCDET_MODE as required for the microphone
detection as such it is redundant to set this outside of this function.

extcon: arizona: Tidy up transition from mic to headphone detect

2019-12-09T11:18:14+00:00

Moving from microphone detection to headphone detection is done fairly
haphazardly at the moment, sometimes calling arizona_stop_mic at the
call site sometimes relying on a call inside arizona_identify_headphone.
Simplify all this and always call arizona_stop_mic at the top of
arizona_identify_headphone.

extcon: arizona: Clear jack status regardless of detection type

2019-12-09T11:18:14+00:00

It makes sense to clear the internal state of the jack detection
regardless of if the headphone detect based accessory detection or
the normal microphone detect based flow is used.

No issues are currently known because of this but the change makes
more logical sense and eases future refactoring of the code.

extcon: arizona: Move pdata extraction to probe

2019-12-09T11:18:14+00:00

It makes no sense to be extracting values from pdata for the first time
in the jack detection handler function, move this to probe time where it
belongs.
