Subject: [PATCH v3 1/4] dt-bindings: media: imx258: add bindings for IMX258 sensor
Add bindings for the IMX258 camera sensor. The bindings, just like the
driver, are quite limited, e.g. do not support regulator supplies.
Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>
---
Changes since v2:
1. Remove clock-frequency, add reset GPIOs, add supplies.
2. Use additionalProperties.
Changes since v1:
1. None
