Subject: [PATCH v5 02/20] dt-bindings: display: tegra: vi: add 'vip' property and example
The Tegra20 VI peripheral can receive parallel input from the VIP parallel
input module. Add it to the allowed properties and augment the existing
nvidia,tegra20-vi example to show a 'vip' property.

Changed in v3 (suggested by Rob Herring):

endpoints
Changed in v2 (suggested by Krzysztof Kozlowski):
- rename "i2c3" -> "ic2"
- add review tag
