[PATCH 1/3] ASoC: rt5682s: Reduce coupling of Micbias and Vref2 settings

[PATCH 1/3] ASoC: rt5682s: Reduce coupling of Micbias and Vref2 settings

[derek.fang]

From: Derek Fang <derek.fang@realtek.com>

Some parts of rt5682s CCF function are implemented by
'MICBIAS' and 'Vref2' dapm widgets.

There is a risk of causing not expected behavior if we
mix using dapm and CCF operations in machine specific code.
This patch reduces the coupling.

[1/3] ASoC: rt5682s: Reduce coupling of Micbias and Vref2 settings

[2/3] ASoC: rt5682s: Reduce coupling of I2S1 setting

[3/3] ASoC: rt5682s: Reduce coupling of PLLB setting
      commit: 3d47637719c312cfb49d3ba063dc3976535c0e9f

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
