Luca Ceresoli Nov. 28, 2022, 3:23 p.m. UTC 
  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.

Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

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

You can drop 'endpoint'. You only need port nodes if there's no extra 
properties in the endpoints.
