[alsa-devel] Applied "ASoC: rt5665: set i2s pin share configuration" to the asoc tree

[Mark Brown]

The patch

   ASoC: rt5665: set i2s pin share configuration

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: rt5665: set i2s pin share configuration

I2S2 and I2S3 are share pins. We need to configure it when i2s is
active and disable it when i2s is inactive. To disable i2s pins
means to set them as gpio.
