Ah. I missed part of the start of the discussion it seems.

On the other hand I think the bigger patch is OK actually.

I rewrote the timer support some time back and did not get
anyone to test it properly at the time, so the patch went in
untested. So this is a fix.

I think this should be applied as-is since you can actually
test the whole thing on real hardware, and also add:

Fixes: f3372c01816e "ARM: gemini: convert to GENERIC_CLOCKEVENTS"

I recently looked at some of the patch stacks in OpenWRT and
get a bit sad that the stuff did not go upstream, so I am ready
to help in any way I can.

Anything GPIO related I am ready to help in reviewing/applying
and I will also help out with ARM32 if I can. Sadly I do not have
a Gemini system.

Yours,
Linus Walleij
