OK. This is confusing. The text was changed after my question about something porch-like
in the SMPTE-125M standard. But I see nothing like that after re-reading it.
So what sort of 'porch' timing were you thinking of?
I wonder if I shouldn't just use the text from your first patch:
- ``V4L2_DV_BT_STD_SDI``
- The timings follow the SDI Timings standard.
There are no horizontal syncs/porches at all in this format.
Total blanking timings must be set in hsync or vsync fields only.
