-* GPIO driven matrix keypad device tree bindings
-
-GPIO driven matrix keypad is used to interface a SoC with a matrix keypad.
-The matrix keypad supports multiple row and column lines, a key can be
-placed at each intersection of a unique row and a unique column. The matrix
-keypad can sense a key-press and key-release by means of GPIO lines and
-report the event using GPIO interrupts to the cpu.
-
-Required Properties:
-- compatible: Should be "gpio-matrix-keypad"
-- row-gpios: List of gpios used as row lines. The gpio specifier
- for this property depends on the gpio controller to
- which these row lines are connected.
-- col-gpios: List of gpios used as column lines. The gpio specifier
- for this property depends on the gpio controller to
- which these column lines are connected.
-- linux,keymap: The definition can be found at
- bindings/input/matrix-keymap.txt
-
-Optional Properties:
-- linux,no-autorepeat: do no enable autorepeat feature.
-- wakeup-source: use any event on keypad as wakeup event.
- (Legacy property supported: "linux,wakeup")
-- debounce-delay-ms: debounce interval in milliseconds
-- col-scan-delay-us: delay, measured in microseconds, that is needed
- before we can scan keypad after activating column gpio
-- drive-inactive-cols: drive inactive columns during scan,
- default is to turn inactive columns into inputs.
-
-Example:
- matrix-keypad {
- compatible = "gpio-matrix-keypad";
- debounce-delay-ms = <5>;
- col-scan-delay-us = <2>;
-
- row-gpios = <&gpio2 25 0
- &gpio2 26 0
- &gpio2 27 0>;
-
- col-gpios = <&gpio2 21 0
- &gpio2 22 0>;
-
- linux,keymap = <0x0000008B
- 0x0100009E
- 0x02000069
- 0x0001006A
- 0x0101001C
