[PATCH v3 02/12] dt-bindings: phy: qcom,ipq5332-uniphy-pcie-usb3: Document the IPQ5018 USB3 PHY

[George Moussalem via B4 Relay <devnull+george.moussalem.outlook.com@kernel.org>]

From: George Moussalem <george.moussalem@outlook.com>

Describe the USB3 PHY found in the IPQ5018 SoC so add the compatible
string for it as well as the required resources (clocks and resets).

The PCIe and USB physical pads are muxed and selection is done via a
control register in TCSR. By default, PCIe mode is selected, hence make
the property for USB mux selection required.

In addition, the PHY requires a 5V supply for USB3 mode operation.
