[PATCH 0/8] arm: ep93xx: CCF conversion

From: Nikita Shubin <nikita.shubin@maquefel.me>
Date: 2021-07-26 11:58:27

This series series of patches converts ep93xx to Common Clock Framework.

It consists of preparation patches to use clk_prepare_enable where it is 
needed, instead of clk_enable used in ep93xx drivers prior to CCF and
a patch converting mach-ep93xx/clock.c to CCF.

This series is looking very good.
Reviewed-by: Linus Walleij <redacted>

I suppose the per-subsystem patches can be picked up by
each subsystem maintainer and then you can send the "big patch"
to the SoC tree.

Thanks!

[2/8] spi: spi-ep93xx: Prepare clock before using it
      commit: 7c72dc56a631b87043e3c5838f5094db30d8c58d

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
