Yes, a bit.
1. Missing reg/unit-address:
Documentation/devicetree/bindings/usb/cypress,cypd4226.yaml
I guess this could be easily solved.

2. phy-supply:
arch/arm64/boot/dts/marvell/armada-3720-turris-mox.dts
(and more of armada)
This is a bit odd:

phy@...00 {
  compatible = "marvell,comphy-a3700";
  comphy0: phy@0 {}
  comphy1: phy@1 {}
  comphy2: phy@2 {
    connector {
      compatible = "usb-a-connector";
      phy-supply = <&exp_usb3_vbus>;
   };
};

I would assume that phy-supply should be a property of the phy.

Best regards,
Krzysztof
