Same as in the other patch, "marvell,pxa270-udc".

OK. I'm presuming in this case you think of something like :
udc-pullup-gpio = <&gpio 22 GPIO_ACTIVE_LOW>
Which translates into:
"udc-pullup-gpio" - gpio activated to control the USB D+ pullup (see
gpio.txt)

Ah you mean I shall describe the standard reg, interrupts as mandatory standard
options I take it. OK.

I don't understand. With [1] does it make any more sense ? If not you'll have to
expand a bit more the "doesn't make sense".
Cheers.
