    V4L/DVB (12906c): V4L : vpif capture driver for DM6467 · 6ffefff5
    Muralidharan Karicheri authored
    This is the vpif capture bridge driver for DM6467.  This video
    supports two video channels each having a tvp5147 device at
    the input. This allows simultaneous capture of NTSC/PAL video
    in each of this channel. Both MMAP and USERPTR io mechanism
    are supported. Currently buffer allocation happens at REQBUF
    ioctl request. Since USERPTR IO is supported, this is not an
    issue since user applications can allocate buffers and pass
    the user space address to the driver. Following are TODOs :-
    	1) Adding support for allocation of buffers at init
    	2) VBI/HBI data service
    
    This has incorporated comments received against version v0
    of the patch series.
