[PATCH v2 0/4] ALSA: pcm: add support for 352.8KHz and 384KHz sample rate

[Srinivas Kandagatla]

This patchset adds missing support to 352.8KHz and 384KHz sample rates in
Qualcomm WCD9335 codec and QDSP dais.

First patch adds these new rates to known list of rates in pcm core and
also adds defines in pcm.h so that drivers can use it.

Changes since v1:
 - Added wcd and qdsp users of these new rates.

  ASoC: wcd9335: Fix primary interpolator max rate
  ASoC: qdsp6: q6afe-dai: Update max rate for slim and tdm dais
  ASoC: qdsp6: q6asm-dai: fix max rates on q6asm dais

[PATCH v2 1/4] ALSA: pcm: add support for 352.8KHz and 384KHz sample rate

[Srinivas Kandagatla]

From: Vidyakumar Athota <vathota@codeaurora.org>

Most of the modern codecs supports 352.8KHz and 384KHz sample rates.
Currenlty HW params fails to set 352.8Kz and 384KHz sample rate
as these are not in known rates list.
Add these new rates to known list to allow them.

This patch also adds defines in pcm.h so that drivers can use it.

This will support a lot more than advertised, e.g. it contains 64000Hz
or 22050Hz.  Is this supposed?  If yes, mention it clearly in the
changelog, too.

Some of the rates inbetween are not in the DSP supported rate list for TDM.

DSP should return error if we try to set any unsupported rate!

The goal with the capabilities is that we should never get as far as
trying to actually set an unsupported rate, we should figure out earlier
on that it won't work and never even try.

Applied "ASoC: wcd9335: Fix primary interpolator max rate" to the asoc tree

[Mark Brown]

The patch

   ASoC: wcd9335: Fix primary interpolator max rate

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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] ALSA: pcm: add support for 352.8KHz and 384KHz sample rate

Most of the modern codecs supports 352.8KHz and 384KHz sample rates.
Currenlty HW params fails to set 352.8Kz and 384KHz sample rate
as these are not in known rates list.
Add these new rates to known list to allow them.

This patch also adds defines in pcm.h so that drivers can use it.
