- samsung,keypad-num-columns: Number of column lines connected to the
keypad controller.
-- 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.
-
- 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.
- 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 specific to linux:
- linux,keypad-no-autorepeat: do no enable autorepeat feature.
- linux,keypad-wakeup: use any event on keypad as wakeup event.
linux,input-no-autorepeat;
