ASoC dapm controls currently don't support more than 2 channels. This is a problem for SOF-based devices where individual volume control cannot be provided on the 4 DMIC input path.
If we want to provide controls for more than 2 channels, this patch suggests a simple solution based on an override of the info callback. For example, in the case with 4 channel DMIC PGAs, a sof_info callback would be used. Mono and stereo cases will keep using the existing dapm info callback.

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
