[PATCH] ASoC: tlv320aic32x4: Fix TAS2505/TAS2521 channel count
The TAS2505/TAS2521 does support up to two channels, LEFT and RIGHT, which are being alternated on the audio data bus by Word Clock, WCLK. This is documented in TI slau472 2.7.1 Digital Audio Interface. Note that both the LEFT and RIGHT channels are only used for audio INPUT, while only the LEFT channel is used for audio OUTPUT.

[1/1] ASoC: tlv320aic32x4: Fix TAS2505/TAS2521 channel count commit: 3694f996be5cb8374bd224f4e5462c945d359843
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
