Subject: [PATCH v4 01/10] dt-bindings: phy: qcom,qmp-usb3-dp: Add DP phy information
This binding only describes the USB phy inside the USB3 + DP "combo"
phy. Add information for the DP phy and describe the sub-nodes that
represent the DP and USB3 phys that exist inside the combo wrapper.
Remove reg-names from required properties because it isn't required nor
used by the kernel driver.
