[PATCH v6 0/2] Add mediatek codec mt6359 driver

[Jiaxin Yu]

Add mediatek codec (MT6359) driver

MT6359 support playback and capture feature.

On downlink path, it includes three DACs for handset, headset,
and lineout path. On unlink path, it includeds three ADCs for
main mic, second mic, 3rd mic, and headset mic.

By scenario, select *_MUX widget to create damp path.
And by select mic_type_mux to choose DMIC/AMIC/....

For example, select these MUX widget to create headset path
(1) DAC In Mux --> "Normal Path"
(2) HP Mux --> "Audio Playback"

v6 changes:
	1. Remove the compatible string in mt6359codec because MFD should be registering the platform device.

v5 changes:
	1. Don't need to unregister the component whic is already relegated to devm.

Thanks!

[1/2] ASoC: mediatek: mt6359: add codec driver

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
