[alsa-devel] [v3] ASoC: AMD: Configure wclk and bclk of master codec
With CCF support in da7219, we can now set the correct rate of wclk and bclk.
Signed-off-by: Akshu Agrawal akshu.agrawal@amd.com --- v2: Removed clk set rate and enable/disable from da7219 ops as da7219 codec takes care of them internally. Clock configuration kept for those codecs where da7219 acts as master of clock. As suggested by Adam Thomson.
v3: As per spec, adau7002 bclk to be minimum of 64x of wclk. Hence, limiting bclk for all codecs. Also, because of this changes done in v2 of this patch have to be brought back.

The patch
ASoC: AMD: Configure wclk and bclk of master codec
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.2
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
