Tue Jul 21 05:46:01 PDT 2026
Add bindings for Camera Subsystem (CAMSS) on the Qualcomm SM8750 platform.
The SM8750 platform provides:
- 6 x CSIPHY (CSI Physical Layer)
- 3 x TPG (Test Pattern Generator)
- 3 x CSID (CSI Decoder)
- 2 x CSID Lite
- 3 x VFE (Video Front End), 5 RDI per VFE
- 2 x VFE Lite, 4 RDI per VFE Lite
