    BTW, as this seems DM644x specific, shouldn't this depend on 
CONFIG_ARCH_DAVINCI_DM644x?

    Or this one, if it selects VIDEO_DM644X_VPBE?

    Hm, "y" shouldn't be the default.

Since VENC/OSD etc are also applicable to other
DaVinci devices, this KConfig entry should probably
be split to refer to them individually and in a generic
way. "depends on" can then be used to make sure only
the relevant ones show up.

Thanks,

Both venc and osd have to be used together always, so might not make a good idea to split. However, I will add a dependency on DM644x, and include others with appropriate patch sets.
