[PATCH v6 0/2] Modify documentation and machine driver for mt8186_rt1019_rt5682s sound card

[Ajye Huang]

v6:
- dmic codec driver: 
  - Modify "FrontMic" to "Front Mic" and "RearMic" to "Rear Mic"
    to consisit with commit 3cfbf07c6d27 mentioned in description.

v5:
- Documentation: 
  - Add #include <dt-bindings/gpio/gpio.h> in order to use
    GPIO_ACTIVE_HIGH.
  - Remove the change-id in message.

v4:
- Documentation: 
  - Fix the FATAL ERROR: Unable to parse input tree.

v3:
- Documentation: 
  - Add an explain example in description.
  - Add the pinctrl-name and pinctrl id in its example.

v2:
- dmic codec driver: 
  - Remove the unnecessary use of_property_read_bool()

v1:
- Documentation: Add dmic-gpios optional prop for two DMICs case.
- dmic codec driver: 
  - "dmic-gpios" property is used for amixer control to switch
     the dmic signal source between the Front and Rear Dmic.

Thanks for the review!

[PATCH v6 2/2] ASoC: mediatek: mt8186-rt5682: Modify machine driver for two DMICs case

[Ajye Huang]

Having two DMICs, a front DMIC and a Rear DMIC,
but only host audio input AUX port0 is used for these two Dmics.
A "dmic-gpios" property is used for a mixer control to switch
the dmic signal source between the Front and Rear Dmic.

Refer to this one as an example,

[PATCH v6 2/2] ASoC: mediatek: mt8186-rt5682: Modify machine driver for two DMICs case

[Ajye Huang]

Having two DMICs, a front DMIC and a Rear DMIC,
but only host audio input AUX port0 is used for these two Dmics.
A "dmic-gpios" property is used for a mixer control to switch
the dmic signal source between the Front and Rear Dmic.

Refer to this one as an example,
commit 3cfbf07c6d27
("ASoC: qcom: sc7180: Modify machine driver for 2mic")

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

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.
