| 2 | |
| 3 | OHCI |
| 4 | |
| 5 | Required properties: |
| 6 | - compatible: Should be "marvell,pxa-ohci" for USB controllers |
| 7 | used in host mode. |
| 8 | |
| 9 | Optional properties: |
| 10 | - "marvell,enable-port1", "marvell,enable-port2", "marvell,enable-port3" |
| 11 | If present, enables the appropriate USB port of the controller. |
| 12 | - "marvell,port-mode" selects the mode of the ports: |
| 13 | 1 = PMM_NPS_MODE |
| 14 | 2 = PMM_GLOBAL_MODE |
| 15 | 3 = PMM_PERPORT_MODE |
| 16 | - "marvell,power-sense-low" - power sense pin is low-active. |
| 17 | - "marvell,power-control-low" - power control pin is low-active. |
| 18 | - "marvell,no-oc-protection" - disable over-current protection. |
| 19 | - "marvell,oc-mode-perport" - enable per-port over-current protection. |
| 20 | - "marvell,power_on_delay" Power On to Power Good time - in ms. |
| 21 | |
| 22 | Example: |
| 23 | |
| 24 | usb0: ohci@4c000000 { |
| 25 | compatible = "marvell,pxa-ohci"; |
| 26 | reg = <0x4c000000 0x100000>; |
| 27 | interrupts = <18>; |
| 28 | marvell,enable-port1; |
| 29 | marvell,port-mode = <2>; /* PMM_GLOBAL_MODE */ |
| 30 | }; |
| 31 | |
| 32 | UDC |
| 33 | |
| 34 | Required properties: |
| 35 | - compatible: Should be "marvell,pxa270-udc" for USB controllers |
| 36 | used in device mode. |
| 37 | - reg: usb device MMIO address space |
| 38 | - interrupts: single interrupt generated by the UDC IP |
| 39 | - clocks: input clock of the UDC IP (see clock-bindings.txt) |
| 40 | |
| 41 | Optional properties: |
| 42 | - gpios: |
| 43 | - gpio activated to control the USB D+ pullup (see gpio.txt) |
| 44 | |
| 45 | Example: |
| 46 | |
| 47 | pxa27x_udc: udc@40600000 { |
| 48 | compatible = "marvell,pxa270-udc"; |
| 49 | reg = <0x40600000 0x10000>; |
| 50 | interrupts = <11>; |
| 51 | clocks = <&pxa2xx_clks 11>; |
| 52 | gpios = <&gpio 22 GPIO_ACTIVE_LOW>; |
| 53 | }; |
