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";

	...
