Is pl011 the uart device? Does it have a node in DT somewhere? If it
does, then we could put the assigned-parents properties in that node so
that when the pl011 probes the uart1 clock has its parent set to
clk_150m. See the "Assigned clock parents and rates" section of
Documentation/devicetree/bindings/clock/clock-bindings.txt.

I will verify this.

Currently the "assigned-clock*" doesn't work for pl011 UART device
node, maybe we will
do some fix for its driver later or other modules.

Why doesn't it work?
