1Generic USB Properties
2
3Optional 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.

17dwc3@4a030000 {
18 compatible = "synopsys,dwc3";
19 reg = <0x4a030000 0xcfff>;
20 interrupts = <0 92 4>
21 usb-phy = <&usb2_phy>, <&usb3,phy>;
22 maximum-speed = "super-speed";
23 dr_mode = "otg";
