3  * v4l2-dv-timings - Internal header with dv-timings helper functions
16  * @t: Timings for the video mode.
30  * typedef v4l2_check_dv_timings_fnc - timings check callback
35  * Returns true if the given timings are valid.
40  * v4l2_valid_dv_timings() - are these timings valid?
58  *	 timings based on capabilities
66  * timings, filtering out any timings that are not supported based on the
78  * v4l2_find_dv_timings_cap() - Find the closest timings struct
84  * @fnc: callback to check if a given timings struct is OK. May be NULL.
87  * This function tries to map the given timings to an entry in the
88  * full list of possible CEA-861 and DMT timings, filtering out any timings
92  * On success it will fill in @t with the found timings and it returns true.
102  * v4l2_find_dv_timings_cea861_vic() - find timings based on CEA-861 VIC
103  * @t:		the timings data.
106  * On success it will fill in @t with the found timings and it returns true.
112  * v4l2_match_dv_timings() - do two timings match?
114  * @measured:	  the measured timings data.
115  * @standard:	  the timings according to the standard.
117  *		the measured timings.
121  * Returns true if the two timings match, returns false otherwise.
131  * @t:		the timings data.
138  * v4l2_detect_cvt - detect if the given timings follow the CVT standard
145  * In other cases, this parameter does not have any effect on timings.
150  * @fmt: the resulting timings.
154  * in with the found CVT timings.
163  * v4l2_detect_gtf - detect if the given timings follow the GTF standard
177  * @fmt: the resulting timings.
181  * in with the found GTF timings.
206  * @t: the timings data.
214  * For different timings reduced fps is allowed if the following conditions
217  *   - For CVT timings: if reduced blanking v2 (vsync == 8) is true.
218  *   - For CEA861 timings: if %V4L2_DV_FL_CAN_REDUCE_FPS flag is true.
