Current frame buffer driver is not covering the most of the functionality of the OMAP2/3 DSS Hardware like multiple outputs and multiple overlay managers supported by OMAP2/3 class of SoC. Again there is no V4L2 interface exposed by the DSS drivers for controlling the video pipelines of the DSS which is highly desirable feature as the video pipelines of the DSS hardware is a natural fit to the V4L2 architecture.If you want to use v4l for video output, don't let me stop you, but I don't see that it has much actual wide use beyond TI PowerPoint presentations about their graphical architecture.
That was my thought as well, but I've encountered at least 2 products this weekend at IBC using the v4l way on omap3. One of the engineers was complaining about the lack of synchronous updates if you move various videoplanes around (think resizing video windows) which makes the video picture end up outside your nice cairo-drawn borders. So yes, it is getting used outside of TI :)
