+Mixel DSI PHY for i.MX8
+
+The Mixel MIPI-DSI PHY IP block is e.g. found on i.MX8 platforms (along the
+MIPI-DSI IP from Northwest Logic). It represents the physical layer for the
+electrical signals for DSI.
+
+Required properties:
+- compatible: Must be:
+ - "mixel,imx8mq-mipi-dphy"
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Must contain the following entries:
+ - "phy_ref": phandle and specifier referring to the DPHY ref clock
+- reg: the register range of the PHY controller
+- #phy-cells: number of cells in PHY, as defined in
+ Documentation/devicetree/bindings/phy/phy-bindings.txt
+ this must be <0>
+
+Optional properties:
+- power-domains: phandle to power domain
+
+Example:
+ mipi_dphy: mipi_dphy@30A0030 {
+ compatible = "mixel,imx8mq-mipi-dphy";
+ clocks = <&clk IMX8MQ_CLK_DSI_PHY_REF>;
+ clock-names = "phy_ref";
+ reg = <0x30A00300 0x100>;
+ power-domains = <&pd_mipi0>;
+ #phy-cells = <0>;
+ };
