[PATCH v2 4/7] media: qcom: camss: Add SM8450 CAMSS support

Mon Oct 26 15:49:54 PDT 2026
Add support of the camera subsystem (CAMSS) found on Qualcomm SM8450 SoC.
The CAMSS IP on SM8450 contains:
* three CSID and two CSID lite, which are supported by CSID 680,
* three VFE and two VFE lite blocks, which are supported by VFE 680,
* three CSI test pattern generators, which are supported by TPG Gen1.
Qualcomm SM8450 CSIPHYs are supported by the CSI2 PHY driver only.
