AK4375 is an audio DAC with headphones amplifier controlled via I2C.
Add simple device tree bindings that describe how to set it up.

Thanks!

[1/2] ASoC: dt-bindings: codecs: Add bindings for ak4375
      commit: 70ba14cf6dfd7ebd1275562bb9637b8d0ddb8f49
[2/2] ASoC: Add AK4375 support
      commit: 53778b8292b5492ec3ecf1efb84163eac2a6e422

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
