Couple of typos you may want to fix

driving?
I must admit I actually don't understand what 'dmic-clk-driving-high' means, a clock is by definition dual-phase and we use both rising and falling edges for the mics.
Or driving high when idle?

That reduces the rising time and falling time while the clock is output, and not driving high always when idle, thanks.

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
