This series adds initial support for the 100ask CanMV-K230 DshanPi
board based on Canaan K230 RISC-V SoC. There is a module on this
development board.

The board and module are documented, the basic board/module devicetrees
are added.

This series is based on the K230 clock series[1] and the patch 3 of the
k230 pinctrl series[2].

Right, I've grabbed patch 3 from [2] and put it on my k230-basic branch.
Do you intend sending a new clock driver series soon? Last time I looked
(about a month ago) you had some changes proposed about critical clocks.
I'd like to try get this stuff merged but obviously it depends on that
clock set. I'll happy send Stephen a PR to smooth things along if the
drivers are ready, but it looks like you need to send another version?

Cheers,
Conor.

I'm not working with Xukai Wang, the developer of the clock series.
I merely discovered the critical clocks during the test and raised
this issue. Regarding the new version of the clock series, you need
to contact Xukai Wang.

I am currently only working on the USB and sd/mmc series of k230.

Ah, my apologies. I clicked the link and when to look at the most recent
activity and your name was on the patch with the fixes to critical clocks,
I guess I never checked to see if you were also the series author. Sorry
about that! Looks like a v10 went out today anyway, so worked out in the
end anyway ;)
