    Subject[PATCH v6 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.

    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
