v4l2_enum_dv_timings_cap — Helper function to enumerate possible DV timings based on capabilities
| int v4l2_enum_dv_timings_cap ( | struct v4l2_enum_dv_timings * t, | 
| const struct v4l2_dv_timings_cap * cap, | |
| v4l2_check_dv_timings_fnc fnc, | |
| void * fnc_handle ); | 
tthe v4l2_enum_dv_timings struct.
capthe v4l2_dv_timings_cap capabilities.
fnccallback to check if this timing is OK. May be NULL.
fnc_handle
     a handle that is passed on to fnc.
    
This enumerates dv_timings using the full list of possible CEA-861 and DMT timings, filtering out any timings that are not supported based on the hardware capabilities and the callback function (if non-NULL).
   If a valid timing for the given index is found, it will fill in t and
   return 0, otherwise it returns -EINVAL.
