[RFC PATCH 0/2] ASoC: mediatek: mt8183-da7219: use SND_SOC_DAPM_PINCTRL
In previous discussion[1], Mark thinks we should have something general pinctrl integration with DAPM. SND_SOC_DAPM_PINCTRL is exactly what we want but I failed to find existing usage (maybe in topology files?).
To be equivalent to mt8183-da7219's original implementation, the 1st patch selects sleep-state at the beginning. The 2nd patch attaches the DAPM widget to playback stream. When the stream is about to start, the power on sequence selects the active-state. When the stream is about to stop, the power off sequence selects the sleep-state.
Note: the DAI links will connect to hdmi-codec, that's why the playback stream name is "I2S Playback". Note: this is a RFC series. If it makes sense, will also apply to mt8183-mt6358.

The patch
ASoC: dapm: select sleep_state when initializing PINCTRL widget
has been applied to the asoc tree at
https://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
