| 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. |
| 14 | |
| 15 | This is an attribute to a USB controller such as: |
| 16 | |
| 17 | dwc3@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"; |
| 24 | }; |
