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.
