The patch
ALSA: pcm: add support for 352.8KHz and 384KHz sample 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

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.
