+title: Mediatek's Keypad Controller device tree bindings
+
+maintainer:
+ - Fengping Yu <fengping.yu@mediatek.com>
+
+description: |
+ Mediatek'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.
+
+properties:
+ compatible:
+ oneOf:
+ - const: "mediatek,mt6779-keypad"
+ - const: "mediatek,mt6873-keypad"
+
+ clock-names:
+ description: Names of the clocks listed in clocks property in the same order
+ maxItems: 1
+ items:
+ - const: kpd
+
+ clocks:
+ description: Must contain one entry, for the module clock
+ refs: devicetree/bindings/clocks/clock-bindings.txt for details.
+
+ interrupts:
+ description: A single interrupt specifier
+ maxItems: 1
+
+ linux,keymap:
+ description: The keymap for keys as described in the binding document
+ refs: devicetree/bindings/input/matrix-keymap.txt
+ minItems: 1
+
+ reg:
+ description: The base address of the Keypad register bank
+ maxItems: 1
+
+ wakeup-source:
+ description: use any event on keypad as wakeup event
+ type: boolean
+
+ keypad,num-columns:
+ description: Number of column lines connected to the keypad controller.
+
+ keypad,num-rows:
+ description: Number of row lines connected to the keypad controller.
+
+ mediatek,debounce-us:
+ description: Debounce interval in microseconds, if not specified, the default
+ value is 16000
+ maximum: 256000
+
+required:
+ - compatible
+ - reg
+ - interrupts
+ - linux,keymap
+ - clocks
+ - clock-names
+
+examples:
+ - |
+
+ kp@10010000 {
+ compatible = "mediatek,kp";
+ reg = <0 0x10010000 0 0x1000>;
+ linux,keymap = < MATRIX_KEY(0x00, 0x00, KEY_VOLUMEDOWN) >;
+ interrupts = <GIC_SPI 75 IRQ_TYPE_EDGE_FALLING>;
