[PATCH] ASoC: dt-bindings: ti,omap4-dmic: Convert to DT schema

[Bhargav Joshi]

Convert the TI OMAP4+ dmic bindings from txt to DT schema.

Following changes are introduced during converson:
  - Drop ti,hwmods property as it is not needed since the sysc
    conversion no existing DTS uses it.
  - Add dma, dma-names, reg-names properties to match the DTS.
  - Update example node to match existing DTS.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-7.3

Thanks!

[1/1] ASoC: dt-bindings: ti,omap4-dmic: Convert to DT schema
      https://git.kernel.org/broonie/sound/c/0f23ed0e117c

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
