The patch
ASoC: bcm2835: Support additional samplerates up to 384kHz
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

Sample rates are only restricted by the capabilities of the clock driver, so use SNDRV_PCM_RATE_CONTINUOUS instead of SNDRV_PCM_RATE_8000_192000.
Tests (eg with pcm5122) have shown that bcm2835 works fine in 384kHz/32bit stereo mode, so change the maximum allowed rate from 192kHz to 384kHz.
