The patch
ASoC: wm_adsp: Move setting of DSP speed into CODEC specific code
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

From: Charles Keepax ckeepax@opensource.wolfsonmicro.com Date: Thu, 21 Jan 2016 17:53:02 +0000 Subject: [PATCH] ASoC: wm_adsp: Move setting of DSP speed into CODEC specific code
The ADSP code should be agnostic of which CODEC it runs upon, currently there is only one remaining part of the implementation that doesn't follow this. When the DSP is booted on ADSP2 we read ARIZONA_SYSTEM_CLOCK_1 and use that to set the initial speed for the DSP clock. This patch factors that out into CODEC specific code, leaving the ADSP code entirely CODEC agnostic.
