[PATCH] ASoC: adau1977: remove platform data and move micbias bindings include
The change removes the platform_data include/definition. It only contains some values for the MICBIAS. These are moved into 'dt-bindings/sound/adi,adau1977.h' so that they can be used inside device-trees. When moving then, they need to be converted to pre-compiler defines, so that the DT compiler can understand them.
The driver then, also needs to include the new 'dt-bindings/sound/adi,adau1977.h' file.

This is missing an update of the binding documentation for the new property.

Umm, if referring to the 'adi,micbias' property, that isn't new: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/tree/Docum...
This just removes any left-over platform-data stuff; which admittedly should have been done earlier. I also started a conversion of the old binding from text to yaml. I'll probably have that ready in a couple of days.

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
