Right now the direction of a DAI has to be specified as a literal
number in the device tree, e.g.:

	dai@0 {
		reg = <0>;
		direction = <2>;
	};

but this does not make it immediately clear that this is a
playback/RX-only DAI.

Actually, q6asm-dai.c has useful defines for this. Move them to the
dt-bindings header to allow using them in the dts(i) files.
The example above then becomes:

	dai@0 {
		reg = <0>;
		direction = <Q6ASM_DAI_RX>;
	};

which is immediately recognizable as playback/RX-only DAI.

Thanks!

[1/1] ASoC: dt-bindings: q6asm: Add Q6ASM_DAI_{TX_RX, TX, RX} defines
      commit: 34facb04228b36006a37727fddee59cf069d95d4

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
