Do you have sysfs interface turned on when building the mainline kernels? Dumb question but it was turned off by default when I was doing my builds. Should be under Device Drivers => GPIO Support -> /sys/class/gpio (sysfs interface) when you do a menuconfig.
yes, I just checked. It is the config option CONFIG_GPIO_SYSFS and this option is set if you use make multi_v7_defconfig to start with an initial config. cheers Harco ||
