This looks all good to me now, it just needs a review for the clk,
reset  and irqchip drivers. I'll won't be pulling any further branches
after the 23rd for this release, so it appears unlikely to still make it
into v5.17, but please keep going anyway. Either Olof will be able
to take the series when I'm gone, or we can do it early for v5.18.

Ideally this should come as a pull request to soc@...nel.org once
you have the remaining Reviewed-by tags, with the text above copied
into the (signed) tag description. If you send it as patches, I'd suggest
adding the text to the description of patch 9/10 instead, where
you add the board code. This way it still becomes part of the git
history for reference.
