Hi everybody, Here is the sixth version of the media controller core and V4L2 patches, and the first one to be sent outside of the linux-media mailing list. For those who haven't heard about the media controller yet, let me quote the documentation (Documentation/DocBook/v4l/media-controller.xml). "Discovering a [media] device internal topology, and configuring it at runtime, is one of the goals of the media controller API. To achieve this, hardware devices are modelled as an oriented graph of building blocks called entities connected through pads." While originally developed to solve problems found in V4L and embedded devices, the API aims at being useful (and hopefully used) by audio drivers as well, especially for devices that combine video and audio capabilities. I want to emphasize that the media controller API does *not* replace the V4L, DVB or ALSA APIs. It complements them. The first user of the media controller API is the OMAP3 ISP driver. You can find it (as well as these patches and other V4L-specific patches) in a git tree at http://git.linuxtv.org/pinchartl/media.git (media-0004-omap3isp branch). The OMAP3 ISP driver patches are regularly posted for review on the linux-media list. I'm looking forward to the storm of comments that will start in response to this e-mail. Hopefully it won't hurt (too much) :-).
