[v4,02/21] dt-bindings: display: tegra: vi: add 'vip' property and example
Commit Message
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.
Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com>

Changed in v4:
- complete the removal of 'channel@0'
Changed in v3 (suggested by Rob Herring):
- drop 'endpoint', unneeded as there's no extra properties in the
endpoints
Changed in v2 (suggested by Krzysztof Kozlowski):
- rename "i2c3" -> "ic2"
- add review tag
