1	Generic USB Properties

3	Optional properties:
4	 - maximum-speed: tells USB controllers we want to work up to a certain
5				speed. Valid arguments are "super-speed", "high-speed",
6				"full-speed" and "low-speed". In case this isn't passed
7				via DT, USB controllers should default to their maximum
8				HW capability.
9	 - dr_mode: tells Dual-Role USB controllers that we want to work on a
10				particular mode. Valid arguments are "host",
11				"peripheral" and "otg". In case this attribute isn't
12				passed via DT, USB DRD controllers should default to
13				OTG.
