-* Samsung's Keypad Controller device tree bindings
-
-Samsung's Keypad controller is used to interface a SoC with a matrix-type
-keypad device. The keypad controller supports multiple row and column lines.
-A key can be placed at each intersection of a unique row and a unique column.
-The keypad controller can sense a key-press and key-release and report the
-event using a interrupt to the cpu.
-
-Required SoC Specific Properties:
-- compatible: should be one of the following
- - "samsung,s3c6410-keypad": For controllers compatible with s3c6410 keypad
- controller.
- - "samsung,s5pv210-keypad": For controllers compatible with s5pv210 keypad
- controller.
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- interrupts: The interrupt number to the cpu.
-
-Required Board Specific Properties:
-- samsung,keypad-num-rows: Number of row lines connected to the keypad
- controller.
-
-- samsung,keypad-num-columns: Number of column lines connected to the
- keypad controller.
-
-- Keys represented as child nodes: Each key connected to the keypad
- controller is represented as a child node to the keypad controller
- device node and should include the following properties.
- - keypad,row: the row number to which the key is connected.
- - keypad,column: the column number to which the key is connected.
- - linux,code: the key-code to be reported when the key is pressed
- and released.
-
-- pinctrl-0: Should specify pin control groups used for this controller.
-- pinctrl-names: Should contain only one value - "default".
-
-Optional Properties:
-- wakeup-source: use any event on keypad as wakeup event.
- (Legacy property supported: "linux,input-wakeup")
-
-Optional Properties specific to linux:
-- linux,keypad-no-autorepeat: do no enable autorepeat feature.
-
-
-Example:
- keypad@100a0000 {
- compatible = "samsung,s5pv210-keypad";
- reg = <0x100A0000 0x100>;
- interrupts = <173>;
- samsung,keypad-num-rows = <2>;
- samsung,keypad-num-columns = <8>;
- linux,input-no-autorepeat;
- wakeup-source;
-
- pinctrl-names = "default";
- pinctrl-0 = <&keypad_rows &keypad_columns>;
-
- key_1 {
- keypad,row = <0>;
- keypad,column = <3>;
- linux,code = <2>;
- };

- key_2 {
- keypad,row = <0>;
- keypad,column = <4>;
- linux,code = <3>;

- key_3 {
- keypad,row = <0>;
- keypad,column = <5>;

Examples
Convert Samsung SoC Keypad bindings to DT schema with changes: 1. Rename "linux,keypad-no-autorepeat" property to "linux,input-no-autorepeat", because the latter was implemented in the Linux driver. 2. Add clocks and clock-names, already used by DTS and the Linux driver.
