Add documentation for device-tree binding of arm PXA 27x udc (usb device) driver. Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Cc: devicetree@vger.kernel.org --- 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 Since V3: Arnd's review - removed clock-names --- Documentation/devicetree/bindings/usb/pxa-usb.txt | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+)
