Subject: [PATCH v8 14/22] dt-bindings: media: camss: Add qcom,msm8916-camss binding
Add bindings for qcom,msm8916-camss in order to support the camera
subsystem on MSM8916.
Signed-off-by: Robert Foss <robert.foss@...aro.org>
Reviewed-by: Rob Herring <robh@...nel.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
Changes since v4:
- Rob: Added r-b
