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";
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 };
