Hans, I have a problem with matching H/V sync polarities. It appears the standard modes use different polarity settings, and HDMI doesn't have separate sync lines, it uses in-band signaling. I don't know what polarity should I set for the v4l2_find_dv_timings_cap() -> v4l2_match_dv_timings() to succeed. 1. I can try all 4 combinations (+/+, +/-, -/+, -/-) and see if there is a match. Seems weird to me. 2. I can add a flag to v4l2_find_dv_timings_cap() -> v4l2_match_dv_timings() which asks for the polarities to be ignored. 3. I could add #define V4L2_DV_VSYNC_POS_POL 0x00000001 #define V4L2_DV_HSYNC_POS_POL 0x00000002 +#define V4L2_DV_VSYNC_ANY_POL 0x00000004 +#define V4L2_DV_HSYNC_ANY_POL 0x00000008 and v4l2_match_dv_timings() would skip comparing them. A bit hacky. 4. I could also add #define V4L2_DV_VSYNC_POS_POL 0x00000001 #define V4L2_DV_HSYNC_POS_POL 0x00000002 +#define V4L2_DV_VSYNC_NEG_POL 0x00000004 +#define V4L2_DV_HSYNC_NEG_POL 0x00000008 and, likewise, v4l2_match_dv_timings() would know what to do. This is IMHO cleaner but requires much more changes in other code (like drivers). Any other idea? Perhaps I should do "2"?
