[libcamera-devel] [libcamera-devel, v2, 1/1] pipeline: simple: Add support for MediaTek MT8365 platforms

[Suhrid Subramaniam]

The camera pipeline for MediaTek MT8365 consists of the following:
Raw sensor (+ external ISP) --> SENINF --> CAMSV30 --> DRAM

SENINF (SENsor INterFace) is a CSI-2 receiver.
CAMSV30 (Camera Simple Version) is a DMA Engine which bypasses
ISP3.0 and writes directly to DRAM.
Both SENINF and CAMSV30 are supported by V4L2 drivers.

MT8365 platform consists of a hardware converter called MDP which
supports up to three streams.
