+* Marvell PXA Keypad controller
+
+Required Properties
+- compatible : should be "marvell,pxa27x-keypad"
+- reg : Address and length of the register set for the device
+- interrupts : The interrupt for the keypad controller
+- marvell,debounce-interval : How long time the key will be
+ recognized when it is pressed. It is a u32 value, and bit[31:16]
+ is debounce interval for direct key and bit[15:0] is debounce
+ interval for matrix key. The value is in binary number of 2ms
+
+Optional Properties For Matrix Keyes
+Please refer to matrix-keymap.txt
+
+Optional Properties for Direct Keyes
+- marvell,direct-key-count : How many direct keyes are used.
+- marvell,direct-key-mask : The mask indicates which keyes
+ are used. If bit[X] of the mask is set, the direct key X
+ is used.
+- marvell,direct-key-low-active : Direct key status register
+ tells the level of pins that connects to the direct keyes.
+ When this property is set, it means that when the pin level
+ is low, the key is pressed(active).
+- marvell,direct-key-map : It is a u16 array. Each item indicates
+ the linux key-code for the direct key.
+
+Optional Properties For Rotary
+- marvell,rotary0 : It is a u32 value. Bit[31:16] is the
+ linux key-code for rotary up. Bit[15:0] is the linux key-code
+ for rotary down. It is for rotary 0.
+- marvell,rotary1 : Same as marvell,rotary0. It is for rotary 1.
+- marvell,rotary-rel-key : When rotary is used for relative axes
+ in the device, the value indicates the key-code for relative
+ axes measurement in the device. It is a u32 value. Bit[31:16]
+ is for rotary 1, and Bit[15:0] is for rotary 0.
+
+Examples:
+ keypad: keypad@d4012000 {
+ keypad,num-rows = <3>;
+ keypad,num-columns = <5>;
+ linux,keymap = <0x0000000e /* KEY_BACKSPACE */
+ 0x0001006b /* KEY_END */
+ 0x00020061 /* KEY_RIGHTCTRL */
+ 0x0003000b /* KEY_0 */

+ 0x02020004 /* KEY_3 */
+ 0x02030005 /* KEY_4 */
+ 0x02040006>; /* KEY_5 */
+ marvell,rotary0 = <0x006c0067>; /* KEY_UP & KEY_DOWN */
+ marvell,direct-key-count = <1>;
+ marvell,direct-key-map = <0x001c>;
+ marvell,debounce-interval = <0x001e001e>;

+TI-NSPIRE Keypad
+
+Required properties:
+- compatible: Compatible property value should be "ti,nspire-keypad".
+
+- reg: Physical base address of the peripheral and length of memory mapped
+ region.
+
+- interrupts: The interrupt number for the peripheral.
+
+- scan-interval: How often to scan in us. Based on a APB speed of 33MHz, the
+ maximum and minimum delay time is ~2000us and ~500us respectively
+
+- row-delay: How long to wait before scanning each row.
+
+- clocks: The clock this peripheral is attached to.
+
+- linux,keymap: The keymap to use
+ (see Documentation/devicetree/bindings/input/matrix-keymap.txt)
+
+Optional properties:
+- active-low: Specify that the keypad is active low (i.e. logical low signifies
+ a key press).
+
+Example:
+
+input {
+ compatible = "ti,nspire-keypad";
+ reg = <0x900E0000 0x1000>;
+ interrupts = <16>;
+
+ scan-interval = <1000>;
+ row-delay = <200>;
+
