 Required properties:
4
- - compatible: brcm,brcmstb-usb-phy
5
- - reg: two offset and length pairs.
6
-	The first pair specifies a manditory set of memory mapped
7
-	registers used for general control of the PHY.
8
-	The second pair specifies optional registers used by some of
9
-	the SoCs that support USB 3.x
