Subject[PATCH v4 14/22] dt-bindings: media: camss: Add qcom,msm8916-camss binding
Date
Add bindings for qcom,msm8916-camss in order to support the camera
subsystem on MSM8916.

Signed-off-by: Robert Foss <robert.foss@linaro.org>
---

Changes since v2:
- Remove redundant descriptions
- Add power domain description
- Make clock-lanes a constant
- Add max & minItems to data-lanes
- Remove ports requirement - endpoint & reg
- Rework to conform to new port schema
