+Broadcom STB USB EHCI controller
+
+Required properties:
+- compatible: should be "brcm,bcm7445-ehci"
+- reg: should contain one register range i.e. start and length
+- interrupts: description of the interrupt line
+- phys: phandle + phy specifier pair
+ The specifier should be 0 for the OHCI/EHCI PHY
+
+Optional properties:
+- clocks: A phandle for the EHCI clock
+
+Example:
+
+ehci@f0b00300 {
+ compatible = "brcm,bcm7445-ehci";
+ reg = <0xf0b00300 0xa8>;
+ interrupts = <0x0 0x5a 0x0>;
