Daniel Mack 73969ff0ed Input: generic driver for rotary encoders on GPIOs
This patch adds a generic driver for rotary encoders connected to GPIO
pins of a system. It relies on gpiolib and generic hardware irqs. The
documentation that also comes with this patch explains the concept and
how to use the driver.
