Subject[PATCH v3 02/21] dt-bindings: display: tegra: vi: add 'vip' property and example
Date
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>
Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com>

---

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
