Huawei Matebook D15 uses 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.
Also, the headset microphone is connected to MIC1, instead of MIC2 port.
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.
The headset microphone also works.
---
v5: - dropped an uneeded differential mux from the boards driver.
v4: - add support for headset microphone on MIC1 port.
v3: - add a patch changing GPIO quirk speaker naming. Patch 2 got rebased on the top of it.
