Thanks for the pointers. I compiled a new kernel from the 3.18rc3 source and made some progress.
There are now gpio devices in /sys: seabass mjo # ls /sys/class/gpio/ export gpiochip338/ gpiochip382/ gpiochip410/ unexport And you can export things: seabass mjo # echo 338 > /sys/class/gpio/export seabass mjo # ls /sys/class/gpio/ export gpio338/ gpiochip338/ gpiochip382/ gpiochip410/ unexport But the GPIO numbers don't match the documentation: seabass mjo # cat /sys/class/gpio/gpiochip*/base 338 382 410 seabass mjo # cat /sys/class/gpio/gpiochip*/ngpio 44 28 102 Is this to be expected ?
