I do have my own patchset that I wanted to send in time for 6.3-rc1,
but the RTC patchset was merged very late so I was waiting for -rc1 to
be out before sending it to Thomas.

I think my DT changes are better as I have no workarounds. I need to
clean up the commits (and have proper commit messages) but you can find
my current work there:

Cheers,
