[PATCH v3] ASoC: dt-bindings: hisilicon: Convert hi6210 I2S to dt-schema

[PATCH v3] ASoC: dt-bindings: hisilicon: Convert hi6210 I2S to dt-schema

[Chaitanya Sabnis]

Convert the Hisilicon hi6210 I2S controller hardware binding from
legacy plain text to modern YAML dt-schema format.

During the conversion, the order of the dma-names properties in the
example was corrected to "tx", "rx" to match the official property
description, resolving a contradiction in the original text binding.

That email hasn't worked for years. I would suggest putting the 
HiSilicon maintainer down for anything HiSilicon related.

Applied to

Thanks!

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
