Could you please help double check this? My understanding is
FB_SYNC_VERT_HIGH_ACT means it's a positive pulse covering all the
valid HSYNCs, and a rising edge of VSYNC means a start of the frame.
However, CFG_INV_VSYNC is '1' means the opposite.
My understanding is that high active means high level trigger new
frame/line. Below page support my point if it is not wrong.

Tried to find the specific diagram in the spec on what CFG_INV_* means
but failed, can you help verified this with an oscilloscope and let know
the result? This is a fix then, and I'd like it to get into .32, sorry for late
reply.
