Hi Mike,

I also hope so. But patch #12 makes those dtb files built
automatically. And patch #13
references clocks that are defined in dt-binding files. If I merge
patch #12 & #13, I'll meet
build issue since I'm lack of those new dt-binding files. So it's
better to go through your
clock tree.

Best Regards
Haojian
