Support multiple endpoints on TLV320AIC3xxx codec port when
used in of_graph context.

This patch allows to share the codec port between two CPU DAIs.

Custom STM32MP255C board uses TLV320AIC3104 audio codec. This codec
is connected to two serial audio interfaces, which are configured
either as rx or tx.

However, when the audio graph card parses the codec nodes, it expects
to find DAI interface indexes matching the endpoints indexes.

The current patch forces the use of DAI id 0 for both endpoints,
which allows to share the codec DAI between the two CPU DAIs
for playback and capture streams respectively.

Applied to

Thanks!

[1/1] ASoC: tlv320aic3x: Add multi endpoint support
      https://git.kernel.org/broonie/sound/c/ed05258250dc

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
