* ST Keyscan controller Device Tree bindings |
|
|
|
The ST keyscan controller Device Tree binding is based on the |
|
matrix-keymap. |
|
|
|
Required properties: |
|
- compatible: "st,sti-keyscan" |
|
|
|
- reg: Register base address and size of st-keyscan controller. |
|
|
|
- interrupts: Interrupt number for the st-keyscan controller. |
|
|
|
- clocks: Must contain one entry, for the module clock. |
|
See ../clocks/clock-bindings.txt for details. |
|
|
|
- pinctrl: Should specify pin control groups used for this controller. |
|
See ../pinctrl/pinctrl-bindings.txt for details. |
|
|
|
- linux,keymap: The keymap for keys as described in the binding document |
|
devicetree/bindings/input/matrix-keymap.txt. |
|
|
|
- keypad,num-rows: Number of row lines connected to the keypad controller. |
|
|
|
- keypad,num-columns: Number of column lines connected to the keypad |
|
controller. |
|
|
|
Optional property: |
|
- st,debounce_us: Debouncing interval time in microseconds |
|
|
|
Example: |
|
|
|
keyscan: keyscan@fe4b0000 { |
|
compatible = "st,sti-keyscan"; |
|
reg = <0xfe4b0000 0x2000>; |
|
interrupts = <GIC_SPI 212 IRQ_TYPE_NONE>; |
|
clocks = <&CLK_SYSIN>; |
|
pinctrl-names = "default"; |
|
pinctrl-0 = <&pinctrl_keyscan>; |
|
|
|
keypad,num-rows = <4>; |
|
keypad,num-columns = <4>; |
|
st,debounce_us = <5000>; |
