1) Where is the QE embedded interrupt controller ?
I think the interrupt-parent of the QE function should point to it.

QEIC is not necessarily to be defined specifically rather=20
than using generic interrupt controller spec.

2) For the UCC, It is better to make rx-clock and tx-clock=20

properties.
 Almost all functions need this properties

Almost is NOT enough to make them required properties for all=20
UCC functions.  There are some devices uses TSA as clock source.

If using TSA, the xx-clock property can use some specific macro to
represent it.
All the UCC need a general clock whether from clocks or TSA.=20
