@ -26,6 +26,14 @@ Optional subnode-properties:
If not specified defaults to 5.
- wakeup-source: Boolean, button can wake-up the system.
(Legacy property supported: "gpio-key,wakeup")
- wakeup-event-action: Specifies whether the key should wake the
system when asserted, when deasserted, or both. This property is
only valid for keys that wake up the system (e.g., when the
"wakeup-source" property is also provided).
Supported values are defined in linux-event-codes.h:
EV_ACT_ASSERTED - asserted
EV_ACT_DEASSERTED - deasserted
EV_ACT_ANY - both asserted and deasserted
- linux,can-disable: Boolean, indicates that button is connected
to dedicated (not shared) interrupt which can be disabled to
suppress events from the button.

Zodiac Inflight Innovations RAVE Supervisory Processor Power Button Bindings
RAVE SP input device is a "MFD cell" device corresponding to power
button functionality of RAVE Supervisory Processor. It is expected
that its Device Tree node is specified as a child of the node
corresponding to the parent RAVE SP device (as documented in
Documentation/devicetree/bindings/mfd/zii,rave-sp.txt)
Required properties:
- compatible: Should be "zii,rave-sp-pwrbutton"
Example:
rave-sp {
compatible = "zii,rave-sp-rdu1";
current-speed = <38400>;
pwrbutton {
compatible = "zii,rave-sp-pwrbutton";
};
}

=======================================================
pxrc - PhoenixRC Flight Controller Adapter
=======================================================
:Author: Marcus Folkesson <marcus.folkesson@gmail.com>
This driver let you use your own RC controller plugged into the
adapter that comes with PhoenixRC [1]_ or other compatible adapters.
The adapter supports 7 analog channels and 1 digital input switch.
Notes
=====
Many RC controllers is able to configure which stick goes to which channel.
This is also configurable in most simulators, so a matching is not necessary.
The driver is generating the following input event for analog channels:
+---------+----------------+
| Channel | Event |
+=========+================+
| 1 | ABS_X |
+---------+----------------+
| 2 | ABS_Y |
+---------+----------------+
| 3 | ABS_RX |
+---------+----------------+
| 4 | ABS_RY |
+---------+----------------+
| 5 | ABS_RUDDER |
+---------+----------------+
| 6 | ABS_THROTTLE |
+---------+----------------+
| 7 | ABS_MISC |
+---------+----------------+
The digital input switch is generated as an `BTN_A` event.
Manual Testing
==============
To test this driver's functionality you may use `input-event` which is part of
the `input layer utilities` suite [2]_.
For example::
> modprobe pxrc
> input-events <devnr>
To print all input events from input `devnr`.
