Subject: Applied "ASoC: sun4i-codec: Add support for A23 codec" to the asoc tree
The patch
ASoC: sun4i-codec: Add support for A23 codec
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

Subject: [PATCH] ASoC: sun4i-codec: Add support for A23 codec
The codec in the A23 is similar to the one found on the A31. One key
difference is the analog path controls are routed through the PRCM
block. This is supported by the sun8i-codec-analog driver, and tied
into this codec driver with the audio card's aux_dev.
In addition, the A23 does not have LINEOUT, and it does not support
headset jack detection or buttons.
