The patch
ASoC: arizona: Attach SYSCLK to DSP preloaders
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

Currently SYSCLK is attached to every compressed DAI as this follows the pattern of attaching clocks to the chips inputs and outputs, however, it is really the DSP that requires the clock here. As firmware download can be a significant part of the path startup time for these devices occasionally it would be desirable to download the firmware in advance of the path being brought up.
To help facilitate this early firmware loading this patch attaches the SYSCLK to the DSP preloader widget. This also saves us adding a new route to SYSCLK every time a new compressed DAI is created.
