Supporting Video (de)serializers in Linux: Challenges and Works in Progress

summary
Kernel has no mainline support for TI FPD‑Link/GMSL and Maxim serializers; patches exist but CSI‑2 stream multiplexing and runtime Device Tree overlay insertion/removal are not merged. Implementation builds a working hot‑plug workaround that pretends sensor always present, instantiates I2C and GPIO adapters in the deserializer, and implements TI address‑translation aliases so remote I2C devices appear on distinct buses. V4L2 still expects fixed pipelines so solution forces nonstandard sensor drivers, but it works without touching serializer drivers.
