Drop support for platform data passed via a C-structure and switch to
device properties instead, which should make the driver compatible with all
platforms: OF, ACPI and static boards. Static boards should use property
sets to communicate device parameters to the driver.

Input: rotary_encoder - convert to use gpiod API2016-03-02T17:31:49ZDmitry Torokhovdmitry.torokhov@gmail.com2016-01-17T18:18:12Zurn:sha1:77a8f0ad38844b5d4163424c4feb8abbbbb55af0
Instead of using old GPIO API, let's switch to GPIOD API, which
automatically handles polarity.

Input: rotary-encoder - add support for quarter-period mode2015-10-16T22:32:18ZEzequiel Garciaezequiel@vanguardiasur.com.ar2015-10-14T06:39:50Zurn:sha1:3a341a4c30d427fd05617087db1564a595f65093
Some encoders have both outputs low in stable states, others also have
a stable state with both outputs high (half-period mode) and some have
a stable state in all steps (quarter-period mode). The driver used to
support the former states and with this change it can also support the
later.
This commit also deprecates the 'half-period' property and introduces
a new property 'steps-per-period'. This property specifies the
number of steps (stable states) produced by the rotary encoder
for each GPIO period.

Input: rotary_encoder - add support for REL_* axes2009-04-18T03:37:21ZH Hartley Sweetenhartleys@visionengravers.com2009-04-18T03:12:35Zurn:sha1:bd3ce6556072bdc8ea66dfd5448e184f189bdc7f
The rotary encoder driver only supports returning input events
for ABS_* axes, this adds support for REL_* axes. The relative
axis input event is reported as -1 for each counter-clockwise
step and +1 for each clockwise step.
The ability to clamp the position of ABS_* axes between 0 and
a maximum of "steps" has also been added.

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.
