The patch

   ASoC: tlv320aic32x4: Properly implement the positive and negative pins into the mixers

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: tlv320aic32x4: Properly implement the positive and
 negative pins into the mixers

The TLV320AIC32x4 has a very flexible mixer on the inputs to the ADCs.  Each
mixer has an available set of available pins that can be connected to the
ADC positive and negative pins via three different resistor values.  This
allows for configuration of differential inputs as well as doing level
manipulation between sources going into the mixers.

The current code only provides positive pins and I implemented the resistors
in an earlier patch.  It turns out that it appears to more accurately model
what's happening to implement each of the pins as a MUX rather than on/off
switches and a mixer.  This way each pin can be set to its desired resistor
value.  Since there are no switches, the mixer is no longer necessary in the
DAPM path.  I set the DAPM paths such that the "off" position of any of the
MUXes turns the path off.

This should allow for any input confiuration available on the codec.
