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"; 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>; };
