[02/23] dt-bindings: display: tegra: vi: add 'vip' property and example
Commit Message
From: Luca Ceresoli <luca.ceresoli@bootlin.com>
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.
