Subject: [PATCH v3 02/21] dt-bindings: display: tegra: vi: add 'vip' property and example
Date:   Thu, 29 Dec 2022 14:31:46 +0100
Message-Id: <20221229133205.981397-3-luca.ceresoli@bootlin.com>
In-Reply-To: <20221229133205.981397-1-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.

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

---

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
