+Device-Tree bindings for input/gpio_keys_polled.c keyboard driver
+
+Required properties:
+        - compatible = "gpio-keys-polled";
+        - poll-interval: Poll interval time in milliseconds
+
+Optional properties:
+        - autorepeat: Boolean, Enable auto repeat feature of Linux input
+          subsystem.
+
+Each button (key) is represented as a sub-node of "gpio-keys-polled":
+Subnode properties:
+
+        - gpios: OF device-tree gpio specification.
+        - label: Descriptive name of the key.
+        - linux,code: Keycode to emit.
+
+Optional subnode-properties:
+        - linux,input-type: Specify event type this button/key generates.
+          If not specified defaults to <1> == EV_KEY.
+        - debounce-interval: Debouncing interval time in milliseconds.
+          If not specified defaults to 5.
+        - gpio-key,wakeup: Boolean, button can wake-up the system.
+
+Example nodes:
+
+        gpio_keys_polled {
+                        compatible = "gpio-keys-polled";
+                        #address-cells = <1>;
+                        #size-cells = <0>;
+                        poll-interval = <100>;
+                        autorepeat;
+                        button@21 {
+                                label = "GPIO Key UP";
+                                linux,code = <103>;
+                                gpios = <&gpio1 0 1>;

+Rotary encoder DT bindings
+
+Required properties:
+- gpios: a spec for two GPIOs to be used
+
+Optional properties:
+- linux,axis: the input subsystem axis to map to this rotary encoder.
+  Defaults to 0 (ABS_X / REL_X)
+- rotary-encoder,steps: Number of steps in a full turnaround of the
+  encoder. Only relevant for absolute axis. Defaults to 24 which is a
+  typical value for such devices.
+- rotary-encoder,relative-axis: register a relative axis rather than an
+  absolute one. Relative axis will only generate +1/-1 events on the input
+  device, hence no steps need to be passed.
+- rotary-encoder,rollover: Automatic rollove when the rotary value becomes
+  greater than the specified steps or smaller than 0. For absolute axis only.
+- rotary-encoder,half-period: Makes the driver work on half-period mode.
+
+See Documentation/input/rotary-encoder.txt for more information.
+
+Example:
+
+                rotary@0 {
+                        compatible = "rotary-encoder";
+                        gpios = <&gpio 19 1>, <&gpio 20 0>; /* GPIO19 is inverted */
+                        linux,axis = <0>; /* REL_X */
+                        rotary-encoder,relative-axis;
+                };
+
+                rotary@1 {
+                        compatible = "rotary-encoder";
+                        gpios = <&gpio 21 0>, <&gpio 22 0>;
+                        linux,axis = <1>; /* ABS_Y */
+                        rotary-encoder,steps = <24>;
+                        rotary-encoder,rollover;
+                };
