Video serializer and deserializer chipsets are more and more used in embedded Linux systems to transmit raw video at several meters distance. Yet the kernel still lacks support for them, despite the attempts seen so far.

Luca will give an overview of the existing chips and the current mainlining attempts. He will then introduce the peculiar requirements of his application and the idea behind his implementation effort.

Special attention will be given to the current limitations of V4L2 and Device Tree that prevent to fully exploit the hotplug features of the chips, and how they influenced his implementation.

The I2C address translation available in some chips, and how to model it in the kernel, will also be covered.
