[PATCH 2/2] ASoC: imx-card: Add playback_only or capture_only support

[Shengjiu Wang]

With the DPCM case, the backend only support capture or
playback, then the linked frontend can only support
capture or playback, but frontend can't automatically
enable only capture or playback, it needs the input
from dt-binding.

audio-graph-port are based on 'port'. which is not used
in imx-card.  imx-card can't directly refer to audio-graph-port.yaml.

[1/2] ASoC: dt-bindings: imx-card: Add playback-only and capture-only property

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
