As of [1] the order should be something like:
1/ compatible
2/ reg
3/ ranges
4/ #address-cells
#size-cells

Please check the rest of the file to comply with this [1]

This one ^

and this one ^ should be alligned as of coding
style (see [1] above). Same for the rest of occurencies I will not comment on.

There is a space at the end of the line.

Same here: add array entry with <>

You have spaces here ^
for queue1..5 but not for q0

Usually the node name for this is poweroff. Any reason you changed it like
this?

Node name should be generic, e.g. clock-controller

microchip,sam9x7-gbpr seems undocummented.
