[PATCH v3 1/3] dt-bindings: phy: qcom,snps-eusb2-phy: Document the Nord eUSB2 PHY

[Bartosz Golaszewski]

Add a compatible for the eUSB2 PHY found on the Qualcomm Nord SoC.
It is compatible with the sm8550 eUSB2 PHY.

While at it: On Nord SoC there are three eUSB2 PHYs but only two QUSB2PHY
block resets: the HS-only USB20 tile has no dedicated PHY reset and is
instead reset as a whole through the controller's own USB20_PRIM_BCR.

Make the 'resets' property optional for qcom,nord-snps-eusb2-phy only,
keeping it required for all the other compatibles.
