+Qualcomm CI13xxx (Chipidea) USB controllers
+
+Required properties:
+- compatible: should contain "qcom,ci-hdrc"
+- reg: offset and length of the register set in the memory map
+- interrupts: interrupt-specifier for the controller interrupt.
+- usb-phy: phandle for the PHY device
+- dr_mode: Should be "peripheral"
+
+Examples:
+ gadget@f9a55000 {
+ compatible = "qcom,ci-hdrc";
+ reg = <0xf9a55000 0x400>;
+ dr_mode = "peripheral";
+ interrupts = <0 134 0>;
+ usb-phy = <&usbphy0>;
+ };
