-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:
-  - "fsl,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:
-	dphy: dphy@30a0030 {
-		compatible = "fsl,imx8mq-mipi-dphy";
-		clocks = <&clk IMX8MQ_CLK_DSI_PHY_REF>;
