[PATCHv2 2/2] arm: Add device trees for TI-Nspire hardware
From: Daniel Tang
Date: Tue Jun 11 2013 - 04:40:56 EST
This patch adds device trees for describing the TI-Nspire hardware.
Changes between v1 and v2:
* Change "keymap" binding to the standard "linux,keymap" binding.

+Required properties:
+- compatible: Compatible property value should contain "ti,nspire".
+ CX models should have "ti,nspire-cx"
