[PATCH 0/6] ASoC: mediatek: mt8183: support DP audio

[PATCH 0/6] ASoC: mediatek: mt8183: support DP audio

[Tzung-Bi Shih]

This series is a follow up for a long time ago series
(https://patchwork.kernel.org/cover/11204303/).

The old series bound too much on the patches of DRM bridge and ASoC
machine driver.  And unluckily, the dependencies
(https://lore.kernel.org/patchwork/patch/1126819/) have not applied.

Revewing the ASoC patches in the old series, I found that they could be
decoupled from the DRM bridge patches.  And they are harmless as it is
an optional attribute ("hdmi-codec") in DTS.

This series arranges and rebases the harmless ASoC patches for
mt8183-mt6358-ts3a227-max98357 and mt8183-da7219-max98357.

The 1st and 4th patch add an optional DT property.  The 1st patch was
acked long time ago (https://patchwork.kernel.org/patch/11204321/).

The 2nd and 5th patch add DAI link for using hdmi-codec.

The 3rd and 6th patch support the HDMI jack reporting.

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
