Changes: v1 --> v2: Suggested by Lucas, don't use the boolean property to specify the different power supplies to PCIe PHY. Use one regulator to power up PCIe PHY, and the regulator APIs to get the voltage of it. [PATCH v2 1/3] dt-bindings: imx6q-pcie: add one regulator used to [PATCH v2 2/3] arm64: dts: imx8mq-evk: add one regulator used to [PATCH v2 3/3] PCI: imx: clear vreg bypass when pcie vph voltage is
