Hi guys,

I have to select a motherboard with GPIO. The GPIO shall be supported by the linux kernel (writing the driver is not an option) and the driver shall support interrupt on input changes (/sysfs/class/gpio/../edge shall exist when a IO is exported as input).

Where can I find a list of the GPIO drivers which support interrupt on input changes?

Thanks

Vincent
