The patch

   ASoC: audio-graph-card: update bindings for amplifier support

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: audio-graph-card: update bindings for amplifier support

The audio-graph-card should be able to support widgets and routing in
the same way as what simple-audio-card does.  The patch adds the
properties into audio-graph-card bindings.  Then an optional property
'pa-gpios' for controlling external amplifier, which depends on DAPM
widgets and routing, is added.
