Subject[PATCH v4 17/22] dt-bindings: media: camss: Add qcom,sdm845-camss binding
Date
Add bindings for qcom,sdm845-camss in order to support the camera
subsystem for SDM845.

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

Changes since v2
- Rob: Removed extra empty lines at end of file
- Rob: Add new line at end of file
- Rob: Remove redundant descriptions
- Rob: Add power domain description
- Rob: Make clock-lanes a constant
- Rob: Rework to conform to new port schema
- Add max & minItems to data-lanes
- Remove ports requirement - endpoint & reg
- Add proper commit message
- Remove Todor as binding maintainer

Changes since v3
- Fixed ordering of IRQs
