-TI-NSPIRE Keypad
-
-Required properties:
-- compatible: Compatible property value should be "ti,nspire-keypad".
-
-- reg: Physical base address of the peripheral and length of memory mapped
- 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:
-- active-low: Specify that the keypad is active low (i.e. logical low signifies
- a key press).
-
-Example:
-
-input {
- compatible = "ti,nspire-keypad";
