-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>;
- };
