||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Compatible property value should be "ti,nspire-keypad".
|
||
|
|
|
||
|
|

|
||
|
|
region.
|
||
|
|
|
||
|
|
- interrupts: The interrupt number for the peripheral.
|
||
|
|
|
||
|
|
- scan-interval: How often to scan in us. Based on a APB speed of 33MHz, the
|
||
|
|
maximum and minimum delay time is ~2000us and ~500us respectively
|
||
|
|
|
||
|
|
- row-delay: How long to wait before scanning each row.
|
||
|
|
|
||
|
|
- clocks: The clock this peripheral is attached to.
|
||
|
|
|
||
|
|
- linux,keymap: The keymap to use
|
||
|
|
(see Documentation/devicetree/bindings/input/matrix-keymap.txt)
|
||
|
|
|
||

|
Optional properties:
