+MSM SoC HSUSB controllers
+
+EHCI
+
+Required properties:
+- compatible: Should contain "qcom,ehci-host"
+- regs: offset and length of the register set in the memory map
+- usb-phy: phandle for the PHY device
+
+Example EHCI controller device node:
+
+ ehci: ehci@f9a55000 {
+ compatible = "qcom,ehci-host";
+ reg = <0xf9a55000 0x400>;
+ usb-phy = <&usb_otg>;
+ };
