It's based on Synopsys IP, but it's Qualcomm's version, and isn't the
1.0.0 Qualcomm's version number for this block?

Also I think it "provides SuperSpeed USB connectivity on some Qualcomm
platforms".

Perhaps "Must contain both com and phy, if property is specified", to
clarify that it's all or nothing.


Looks good otherwise.

This is in no way specific enough.

Does the phy actually get supplied by Vbus? If not, then Vbus supply 
should be defined in a USB connector node.

COR or COM?

Looks to me the order is reversed.

ok. will remove the old unused bindings and reuse qcom,dwc3-ss-usb-phy

yes per the documentation vbus can optionally be routed to the phy to
drive a signal to the controller.

funny enough when vbus is optionally routed to the phy is not to be
controlled like we do when the vbus-supply property is present.

So to all effects no, you are right, the phy does not get supplied by VBUS.

would defining the connector like this be enough?

usb3_phy: usb3-phy@78000 {
	compatible = "qcom,snps-usb-ssphy";
	[...]
	usb3_c_connector: usb3-c-connector {
		compatible = "usb-c-connector";
		label = "USB-C";
		type = "micro";
		vbus-supply = <&usb3_vbus_reg>;
	};
};

IIRC, the connector node is defined to go under either the USB
controller or a USB-C controller (if a separate chip controlling the
USB-PD and alternate modes). We generally don't put PHYs into a node
topology, but keep them as a phandle reference.
