AMCC 460EX GPIO

[musaab ali]

Hi there,

I'm using the Canyonlands evaluation board for the ppc 460ex processor. I want to access the GPIO pins, set its direction and set/get their values.
Is there is any common driver to do so? I went throught the Documentation/gpio.txt and the arch/powerpc/sysdev/ppc4xx_gpio.c but I don't know 
how to test the later driver either from kernel space or from user space. Any ideas or sample codes?

Thanks in advance.

Musaab.
