HSYNC - normal polarity and edge triggered?

I've been going through the IMX6 manual and can't find a definitive statement of how HSYNC works on the CSI parallel inputs.

Is the normal polarity "High"? (I know you can invert with CSIx_HSYNC_POL, but which is it normally?)

Is the hsync triggered by the rising edge? Does it care how long it is high for?      And consequently if we had a positive going HRef signal (i.e. it stays high for all of the line's active data), would this still work?

 

 

Just trying to get a UYVY camera going on the parallel input. Based on some OV5640 example from eConSystems. Hoping to use Gstreamer once it's working.

Thanks.
