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.

New subject: [PATCH v5 1/4] ASoC: Intel: sof_es8336: simplify speaker gpio naming

From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com

In preparation for the support of an additional gpio for headphone control, rename GPIOs to make explicit references to speakers and gpio0 or gpio1.

No functionality change.

New subject: [PATCH v5 2/4] ASoC: Intel: sof_es8336: support a separate gpio to control headphone

Some devices may use both gpio0 and gpio1 to independently switch the speaker and the headphone.

Add support for that.

New subject: [PATCH v5 3/4] ASoC: Intel: sof_es8336: add a quirk for headset at mic1 port

The headset/internal mic can either be routed as mic1/mic2 or vice-versa.

By default, the driver assumes that the headset is mapped as mic2, but not all devices map this way.

So, add a quirk to support changing it to mic1, using mic2 for the internal analog mic (if any).

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks, Mark
