[alsa-devel] Applied "ASoC: msm8916-wcd-analog: Add MIC BIAS Internal3" to the asoc tree

[Mark Brown <broonie@kernel.org>]

The patch

   ASoC: msm8916-wcd-analog: Add MIC BIAS Internal3

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

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: msm8916-wcd-analog: Add MIC BIAS Internal3

PM8916 has three TX inputs that each have an (optional) internal
RBIAS resistor. MIC BIAS Internal1/2 (for TX1/2) are already supported.
TX3 does not have its own MIC BIAS supply, instead it is also supplied
from MIC_BIAS1.

Now that we have simplified the MIC BIAS Internal* implementation
we can easily add support for it:

Add a MIC BIAS Internal3 supply that enables the internal RBIAS
resistor on TX3, and make sure to also enable the MIC_BIAS1 supply.
