TI-NSPIRE calculators
Required properties:
- compatible: Compatible property value should contain "ti,nspire".
CX models should have "ti,nspire-cx"
Touchpad models should have "ti,nspire-tp"
Clickpad models should have "ti,nspire-clp"
Example:
/ {
model = "TI-NSPIRE CX";
compatible = "ti,nspire-cx";
