FDT Support for GPIO (gpiobus and friends)

[Luiz Otavio O Souza]

Hi,

I've been playing with GPIO on RPi and found the missing support of FDT on gpiobus very annoying.

The following patch (gpio-fdt.diff) adds FDT support to GPIO (gpiobus, gpioc, gpioled).

The bcm2835_gpio.c.fdt.diff will add (a better) support of FDT on RPi GPIO controller and the bcm2835.dts.diff has my changes on the RPi dts for adding support of gpioled on 'ok' led (pin 16).

Comments ?

Thanks,
Luiz
