[alsa-devel] [PATCH] ASoC: rt5665: force using PLL if MCLK is not suitable
Idealy PLL will be set in machine driver if MCLK doesn't meet the requirement of codec. To let the codec driver be more general, we can use a common PLL setting once sysclk/pll doesn't set properly in machine driver.

The patch
ASoC: rt5665: force using PLL if MCLK is not suitable
has been applied to the asoc tree at
git://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
