Hi -
This RFC patchset is a pretty straightforward adaptation of OMAP GPIO
switch framework for mainline integration.
The GPIO switch framework allows reporting and changing GPIO switches
via sysfs, with debouncing and sysfs/in-kernel notifications for input
switches.
The switches are added as /sys/class/gpio/switch-<switch name> under
the gpiolib sysfs structure.
BR,
Jani.
