Current = frame buffer driver is not covering the most of the functionality of the OM= AP2/3 DSS Hardware like multiple outputs and multiple overlay managers supp= orted by OMAP2/3 class of SoC.

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. > We have already initiated the re-designing of the DSS drivers and already= posted the RFC for the same on the Linux-Omap and the V4L2 mailing lists. = Below is the link for the RFC submitted by us on the open source mailing l= ists - >=20 > http://lists-archives.org/video4linux/23648-omap3-display-driver-v4l2.html > http://www.mail-archive.com/linux-omap@vger.kernel.org/msg02510.html I like this proposal a lot better, but I think fbdev + v4l is not a great plan. Have you looked at DRM modesetting drivers?
