Subject: Applied "ASoC: amd: Enabling I2S instance in DMA and DAI" to the asoc tree
The patch
ASoC: amd: Enabling I2S instance in DMA and DAI
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6
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

Subject: [PATCH] ASoC: amd: Enabling I2S instance in DMA and DAI
This patch adds I2S SP support in ACP PCM DMA and DAI.
Added I2S support in DMA and DAI probe,its hw_params handling
its open and close functionalities.
This enables to open and close on the SP instance for
playback and capture.
