The patch
ASoC: rsnd: add rsnd_runtime_channel_xxx()
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

Subject: [PATCH] ASoC: rsnd: add rsnd_runtime_channel_xxx()
Current SSI is supporting Normal SSI/Multi mode SSI/TDM mode SSI
and its behavior is based on input channels.
This input channel might be converted by CTU,
and SSI needs to be Multi SSI mode / TDM SSI mode if 6ch input
EX) 6ch input, CTU for 2ch, playback
6ch 6ch 2ch 2ch 2ch 2ch
-> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI
EX) 6ch input, no CTU, Multi SSI, playback
6ch 6ch 6ch 6ch 6ch 2ch
-> SRC -> CTU -> MIX -> DVC -> SSIU -> SSI0/SSI1/SSI2
Current driver is using rsnd_get_adinr_chan() / rsnd_get_slot_width()
for this purpose, but it is complicated enough without meaning.
This patch adds new rsnd_runtime_channel_xxx() which is caring
CTU/Multi SSI.
