[alsa-devel] [PATCH 0/3] ASoC: pcm3168a: add TDM support
Hi Mark, Jaroslav
These patches adds missing TDM support, and necessary patches for it.
Kuninori Morimoto (3): ASoC: pcm3168a: add HW constraint for non RIGHT_J ASoC: pcm3168a: add hw constraint for channel ASoC: pcm3168a: add I2S/Left_J TDM support

RIGHT_J only can handle 16bit data bits. Current driver just errored if user requests non RIGHT_J + 16bit combination. But it is not useful for user. This patch adds HW constraint for it, and avoid error on such situation.

The patch
ASoC: pcm3168a: add HW constraint for non RIGHT_J
has been applied to the asoc tree at
https://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 to this mail.
Thanks, Mark
