Subject: Applied "ASoC: rockchip_max98090: Optionally support HDMI use case" to the asoc tree
The patch
ASoC: rockchip_max98090: Optionally support HDMI use case
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5
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

Subject: [PATCH] ASoC: rockchip_max98090: Optionally support HDMI use case
Support three different use cases with rockchip_max98090 driver.
The three use cases:
- max98090 only: Current usage, where HDMI link is missing.
- HDMI only: Needed use case for veyron_mickey board.
- max98090 + HDMI: Ideal use case for veyron_jerry, veyron_minnie..etc.
The presence of max98090 is determined by the presence of
rockchip,audio-codec device property.
The presence of HDMI is determined by the presence of
rockchip,hdmi-codec device property.
Create different sound card based on the configuration.
Note that we keep max98090 only usage for backward compatibility.
