Subject: [PATCH v5 1/2] dt-bindings: imx6q-pcie: Add "vph-supply" for PHY supply voltage

The i.MX8MQ PCIe PHY can use either a 1.8V or a 3.3V power supply.
Add a "vph-supply" property to indicate which regulator supplies
power for the PHY.

For DT bindings you must CC [email protected], please resend.
