Can you convert this binding to YAML? Makes it easier to validate it
against the dts files.
- reg : shall contain base register location and length
- #clock-cells : shall contain 1
- #reset-cells : shall contain 1
+For MSM8998 only:

I'm not sure why it's optional. The hardware is "fixed" in the sense
that the dp phy is always there and connected to this hardware block.
From a driver perspective I agree it's optional to be used, but from a
DT perspective it's always there so it should be required.
