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"; |
