Subject: [PATCH v4 2/6] media: dt-bindings: Add CAMSS device for Kaanapali
Add the compatible string "qcom,kaanapali-camss" to support the Camera
Subsystem (CAMSS) on the Qualcomm Kaanapali platform.
The Kaanapali (SM8550) platform provides:
- 3 x VFE, 5 RDI per VFE
- 2 x VFE Lite, 4 RDI per VFE Lite
- 3 x CSID
- 2 x CSID Lite
- 6 x CSIPHY
