v4:
Change node name
Remove blank line
'make CHECK_DTBS=y DT_SCHEMA_FILES=qcom qcom/ipq5332-rdp441.dtb' passed
v1:
Rename phy node
Change compatible from m31,ipq5332-usb-hsphy -> qcom,ipq5332-usb-hsphy
Remove 'qscratch' from phy node
Fix alignment and upper-case hex no.s
Add clock definition for the phy
Remove snps,ref-clock-period-ns as it is not used. dwc3_ref_clk_period()
in dwc3/core.c takes the frequency from ref clock and calculates fladj
as appropriate.

So you responded to my comments, wait ten minutes and send v2? No need
to wait for my feedback, right?

No, it's not ok. This is "usb", not "usb2". Are you saying you have
second device with the same address?

Just to emphasise, it's the node name `usb2', which is not fine. DT label `usb2' is (hopefully) fine.
