+* Cadence USB3 Controller
+
+Required properties:
+- compatible: should contain: "cdns,usb3-1.0.0"
+- reg: physical base address and size of the controller's register areas
+ Controller has 5 different regions:
+ region 1 - NONE-CORE registers area
+ region 2 - HOST registers area
+ region 3 - DEVICE registers area
+ region 4 - PHY registers area
+ region 5 - OTG registers area
+- reg-names - register memory area names:
+ "none-core" - for NONE-CORE registers space
+ "xhci" - for HOST registers space
+ "dev" - for DEVICE registers space
+ "phy" - for PHY registers space
+ "otg" - for OTG registers space
+- interrupts: interrupts used by cdns3 controller
+- interrupt-parent: the interrupt parent for this module
+- clocks: reference to the USB clock
+- clock-names: the name of clocks
+- phys: reference to the USB PHY
+
+Optional properties:
+- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
+- extcon: extcon phandler for cdns3 device
+- power-domains: the power domain for cdns3 controller and phy
+
+Examples:
+
+usbotg3: cdns3@5b110000 {
+ compatible = "cdns,usb3-1.0.0";
+ reg = <0x0 0x5B110000 0x0 0x10000>,
+ <0x0 0x5B130000 0x0 0x10000>,
+ <0x0 0x5B140000 0x0 0x10000>,
+ <0x0 0x5B160000 0x0 0x40000>,
+ <0x0 0x5B120000 0x0 0x10000>;
+ reg-names = "none-core", "xhci", "dev", "phy", "otg";
+ interrupt-parent = <&gic>;
+ interrupts = <GIC_SPI 271 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clk IMX8QM_USB3_LPM_CLK>,
+ <&clk IMX8QM_USB3_BUS_CLK>,
+ <&clk IMX8QM_USB3_ACLK>,
+ <&clk IMX8QM_USB3_IPG_CLK>,
+ <&clk IMX8QM_USB3_CORE_PCLK>;
+ clock-names = "usb3_lpm_clk", "usb3_bus_clk", "usb3_aclk",
+ "usb3_ipg_clk", "usb3_core_pclk";
+ power-domains = <&pd_conn_usb2>;
+ phys = <&usbphy1>;
+ dr_mode = "otg";
+ extcon = <&typec_ptn5150>;
+ status = "disabled";
