The patch

   ASoC: ak4458: Add support for AK4497

has been applied to the asoc tree at

   https://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: ak4458: Add support for AK4497

AK4497 is a 32-bit 2ch DAC and has the same register
map as AK4458 with few exceptions:

* AK4497 has one more register at the end of register space
  DFS_READ which is a read only register that allows users
  to read FS Auto Detection mode. We currently do not use
  this register so we use the same regmap structure as for ak4458.

* Because AK4458 is an 8ch DAC there are some fields that are
  only used by AK4458 and marked as reserved for AK4497, so for
  this reason we need to have a distinct set of controls, widgets
  and routes.

Datasheet for AK4497 is at:
https://www.akm.com/akm/en/file/ev-board-manual/AK4497EQ.pdf

Datasheet for AK4458 is at:
https://www.akm.com/akm/en/file/datasheet/AK4458VN.pdf
