Subject: [RESEND, V5 1/2] dt-bindings: imx6q-pcie: Add "vph-supply" for PHY supply voltage
Date: Fri,  4 Jun 2021 09:47:48 +0800	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

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.
