This patch set is to add new cpu dai, refactor dai format
implementation and clock enable/disable and add tdm support
in acp machine driver.

Changes since v1:
    -- Fix compilation error.
    -- Reorder patch series.
    -- Modify commit message.
    -- Refactor i2s clocks programming sequence.

[PATCH v2 1/5] ASoC: amd: acp: Add new cpu dai's in machine driver

[Venkata Prasad Potturu]

when using same cpu dai for 2 different dai links
below error is reported.
error: can't find BE for DAI ACPHS_VIRTUAL1.OUT

To avoid this error add new cpu dai.

[PATCH v2 3/5] ASoC: amd: acp: Refactor i2s clocks programming sequence

[Venkata Prasad Potturu]

Refactor i2s clock values based on hw_params and use srate and
bclk_ratio variables in clock enable API instead hard-code values.

This last line looks suspicious, no? format-to-physical-size conversions
should be using existing macros.

Should it be

format = params_physical_width(params);

?

not only that, but the "8 * params_format(params)" is certainly not
correct for the purpose.

params_format() returns SNDRV_PCM_FORMAT_*, which is basically an enum:
SNDRV_PCM_FORMAT_S8		0
SNDRV_PCM_FORMAT_S16_LE		2
SNDRV_PCM_FORMAT_S24_LE		6
SNDRV_PCM_FORMAT_S24_3LE	32
SNDRV_PCM_FORMAT_S32_LE		10

I believe this was the intention.

Yes, we will use params_physical_width(params) and update it in the next 
patch.

Thanks for the information.

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
