Merge branch 'nspire/soc' into next/late
From Daniel Tang <dt.tangr@gmail.com> This is the initial platform code for the TI-Nspire graphing calculators. The platform support is rather unspectacular, but still contains platform data for the LCD panel, which will get removed once there is a DT binding for the AMBA CLCD driver. * nspire/soc: arm: Add Initial TI-Nspire support arm: Add device trees for TI-Nspire hardware Signed-off-by: Olof Johansson <olof@lixom.net>

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"
|

/ {
|

model = "TI-NSPIRE CX";
|

compatible = "ti,nspire-cx";
