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@f0b02000 {

                compatible = "brcm,bdc-udc-v2";

                reg = <0xf0b02000 0xfc4>;

                interrupts = <0x0 0x60 0x0>;

                phys = <&usbphy_0 0x0>;

                clocks = <&sw_usbd>;

        };
