Add documentation for device-tree binding of arm PXA 27x udc (usb device) driver. Signed-off-by: Robert Jarzmik <robert.jarzmik@xxxxxxx> Cc: devicetree@xxxxxxxxxxxxxxx --- Since V1: change OF id mrvl,pxa27x_udc -> marvell,pxa27x-udc This is a consequence of other DT reviews on the marvell namings. Since V2: Mark's review - described standard properties - use standard gpio bindings for pullup gpio --- Documentation/devicetree/bindings/usb/pxa-usb.txt | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) diff --git a/Documentation/devicetree/bindings/usb/pxa-usb.txt b/Documentation/devicetree/bindings/usb/pxa-usb.txt index 79729a9..028d988 100644 --- a/Documentation/devicetree/bindings/usb/pxa-usb.txt +++ b/Documentation/devicetree/bindings/usb/pxa-usb.txt @@ -29,3 +29,26 @@ Example: 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>; + clock-names = "udc"; + gpios = <&gpio 22 GPIO_ACTIVE_LOW>; + }; -- 2.0.0.rc2 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
