Subject: [PATCH v3 0/3] Make headphone work on Huawei Matebook D15
Date:   Tue,  5 Apr 2022 18:57:31 +0200

At Huawei Matebook D15 two different GPIOs are used to control the output:
	- gpio0 controls the speaker output;
	- gpio1 controls the headphone output.

Changing both at the same time cause spurious events that are mis-interpreted
as input events, causing troubles on apps. So, a delay is needed before turning
on such gpios.

With this patch, plugging a headphone causes a jack event to trigger the speaker
supply, powering down the speaker and powering up the headphone output.
Removing the headphone also triggers the power supply, powering up the speaker
and powering down the headphone.

v3:
  - add a patch changing GPIO quirk speaker naming. Patch 2 got rebased on the top of it.
