Hi Hal,

Firstly thanks for working on this! And sorry about the late reply. On
the next version could you please cc
emil.renner.berthing@xxxxxxxxxxxxx since it seems to handle the
mailing list a bit better.

I see you've changed the clock/reset and pinctrl quite a bit, so I'll
comment on that separately.
