No problem, thanks for helping on this

The clock driver's review is still on-going, the biggest concern is about
the mix clock implementation [1], which isn't decent, and Haylen's working on
to have a better version, I'd hope we can catch this in 6.14's merge window..

But, in the worst case if we have to postpone clock to next merge window,
would you think it's ok to push the basic dts and pinctrl dts first?
IMHO, they have no hard dependency on clock driver, and pushing them
first would simplify the future developement..
