[PATCH v5] ASoC: mediatek: Add second I2S on mt8173-rt5650 machine driver

[PATCH v5] ASoC: mediatek: Add second I2S on mt8173-rt5650 machine driver

[PC Liao]

This patch adds second I2S connection to rt5650 codec for capture path on
mt8173-rt5650 machine driver.

This patch depends on [1], because snd_soc_of_get_dai_name() fix the property 
name "sound-dai". This patch needs to change name to use, so export
snd_soc_get_dai_name() which is included in snd_soc_of_get_dai_name().

snd_soc_get_dai_name")

Changes since v4:
Change name from "sound-dai" to "capture-dai" to determine the capture path

Applied "ASoC: mediatek: Add second I2S on mt8173-rt5650 machine driver" to the asoc tree

[Mark Brown]

The patch

   ASoC: mediatek: Add second I2S on mt8173-rt5650 machine driver

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

I think it also needs to apply [1], otherwise this patch will build
