Supporting the Camera Interface on the C.H.I.P - Maxime Ripard, Free Electrons
Every modern multimedia-oriented ARM SoC usually has some kind of camera interface to be able to capture a video (or photo) stream from an external camera. The framework of choice to support these controllers in Linux is the Video4Linux subsystem, also called v4l2.
This talk will walk through the v4l2 stack, the architecture of a v4l2 driver and the interaction between the SoC driver and its camera's.
The presentation is based on the work we have done to develop such a driver for the Allwinner SoCs, as part of enabling the C.H.I.P platform with the upstream Linux kernel.
