The patch ASoC: amd: Adding TDM support in hw_params. 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.

Thanks, Mark >From ab985be95da1d68a0cdba1ed702961aae047bf89 Mon Sep 17 00:00:00 2001 From: Ravulapati Vishnu vardhan rao <Vishnuvardhanrao.Ravulapati@xxxxxxx> Date: Mon, 9 Mar 2020 16:20:10 +0530 Subject: [PATCH] ASoC: amd: Adding TDM support in hw_params. TDM related settings for ACP registers in hw_params. When TDM mode is enabled, Hw_params needs to read and write from/to respective TX/RX (ACP_(I2S/BT)TDM_(TX/RX)FRMT) registers.
