Subject: [RFC PATCH 0/3] GPIO switch framework


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.
