-Broadcom USB Device Controller (BDC)
-====================================
-
-Required properties:
-
-- compatible: must be one of:
-                "brcm,bdc-udc-v2"
-                "brcm,bdc"
-- reg: the base register address and length
-- interrupts: the interrupt line for this controller
-
-Optional properties:
-
-On Broadcom STB platforms, these properties are required:
-
-- phys: phandle to one or two USB PHY blocks
-        NOTE: Some SoC's have a single phy and some have
-        USB 2.0 and USB 3.0 phys
-- clocks: phandle to the functional clock of this block
-
-Example:
-
-        bdc@...02000 {
-                compatible = "brcm,bdc-udc-v2";
-                reg = <0xf0b02000 0xfc4>;
-                interrupts = <0x0 0x60 0x0>;
-                phys = <&usbphy_0 0x0>;
-                clocks = <&sw_usbd>;
-        };
