[PATCH v5 0/4] Make headphone work on Huawei Matebook D15

[Mauro Carvalho Chehab]

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.

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

[Mauro Carvalho Chehab]

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.

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

[Mauro Carvalho Chehab]

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

Add support for that.

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

[Mauro Carvalho Chehab]

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).

[PATCH v5 4/4] ASoC: Intel: sof_es8336: Add a quirk for Huawei Matebook D15

[Mauro Carvalho Chehab]

Based on experimental tests, Huawei Matebook D15 actually uses
both gpio0 and gpio1: the first one controls the speaker, while
the other one controls the headphone.

Also, the headset is mapped as MIC1, instead of MIC2.

So, add a quirk for it.

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

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
