| PXA USB controllers |
| |
| OHCI |
| |
| Required properties: |
| - compatible: Should be "marvell,pxa-ohci" for USB controllers |
| used in host mode. |
| |
| Optional properties: |
| - "marvell,enable-port1", "marvell,enable-port2", "marvell,enable-port3" |
| If present, enables the appropriate USB port of the controller. |
| - "marvell,port-mode" selects the mode of the ports: |
| 1 = PMM_NPS_MODE |
| 2 = PMM_GLOBAL_MODE |
| 3 = PMM_PERPORT_MODE |
| - "marvell,power-sense-low" - power sense pin is low-active. |
| - "marvell,power-control-low" - power control pin is low-active. |
| - "marvell,no-oc-protection" - disable over-current protection. |
| - "marvell,oc-mode-perport" - enable per-port over-current protection. |
| - "marvell,power_on_delay" Power On to Power Good time - in ms. |
| |
| Example: |
| |
| usb0: ohci@4c000000 { |
| compatible = "marvell,pxa-ohci", "usb-ohci"; |
| reg = <0x4c000000 0x100000>; |
| interrupts = <18>; |
| marvell,enable-port1; |
| marvell,port-mode = <2>; /* PMM_GLOBAL_MODE */ |
| }; |
| |
| UDC |
| |
| Required properties: |
| - compatible: Should be "marvell,pxa270-udc" for USB controllers |
| used in device mode. |
| - reg: usb device MMIO address space |
| - interrupts: single interrupt generated by the UDC IP |
| - clocks: input clock of the UDC IP (see clock-bindings.txt) |
| |
| Optional properties: |
| - gpios: |
| - gpio activated to control the USB D+ pullup (see gpio.txt) |
| |
| Example: |
| |
| pxa27x_udc: udc@40600000 { |
| compatible = "marvell,pxa270-udc"; |
| reg = <0x40600000 0x10000>; |
| interrupts = <11>; |
| clocks = <&pxa2xx_clks 11>; |
| gpios = <&gpio 22 GPIO_ACTIVE_LOW>; |
| }; |
