+LM8333 Keypad
+
+Required properties:
+- compatible: Compatible property value should be "ti,lm8333".
+
+- reg: Physical base address of the peripheral and length of memory mapped
+ region.
+
+- interrupts: The interrupt number for the peripheral.
+
+- linux,keymap: The keymap to use
+ (see Documentation/devicetree/bindings/input/matrix-keymap.txt)
+
+Optional properties:
+- ti,active-time-ms: Specify the time during which the keypad is scanned after
+ the last key is released, before entering Halt mode.
+ The active time must be longer than the debounce time.
+ Default 500 ms.
+
+- debounce-delay-ms: Specify the keypad debounce time.
+ This can be used for reliable scanning of keyboards with noisy contacts.
+ Default 10 ms.
+
+Example:
+input {
+ compatible = "ti,lm8333";
+ reg = <0x51>;
+ interrupts = <5>;
+
+ ti,active-time-ms = <750>;
+ debounce-delay-ms = <20>;
+
+ linux,keymap = <
