1	PXA USB controllers
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", "usb-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			};
