* GPIO driven matrix keypad device tree bindings
2+
3+
GPIO driven matrix keypad is used to interface a SoC with a matrix keypad.
4+
The matrix keypad supports multiple row and column lines, a key can be
5+
placed at each intersection of a unique row and a unique column. The matrix
6+
keypad can sense a key-press and key-release by means of GPIO lines and
7+
report the event using GPIO interrupts to the cpu.
8+
9+
Required Properties:
10+
- compatible: Should be "gpio-matrix-keypad"
11+
- row-gpios: List of gpios used as row lines. The gpio specifier
12+
for this property depends on the gpio controller to
13+
which these row lines are connected.
14+
- col-gpios: List of gpios used as column lines. The gpio specifier
15+
for this property depends on the gpio controller to
16+
which these column lines are connected.
17+
- linux,keymap: The definition can be found at
18+
bindings/input/matrix-keymap.txt
19+
20+
Optional Properties:
21+
- linux,no-autorepeat: do no enable autorepeat feature.
22+
- linux,wakeup: use any event on keypad as wakeup event.
23+
- debounce-delay-ms: debounce interval in milliseconds
24+
- col-scan-delay-us: delay, measured in microseconds, that is needed
25+
before we can scan keypad after activating column gpio
26+
27+
Example:
28+
matrix-keypad {
29+
compatible = "gpio-matrix-keypad";
30+
debounce-delay-ms = <5>;
31+
col-scan-delay-us = <2>;
