This patch will get the DT parameters of vsync/hsync/pixclock polarity, and
pass to driver.

Also add a debug information for test purpose.

Changes in v2:
- rewrite the debug message and add pix clock polarity setup thanks to
   Laurent.
- update the commit log.

You forgot " edge" right before "\n" :-)

oops, I missed the word.

How about has_emb_sync, which can be set from ep.bus_type ?

yes, right. I forgot this as well.
I'll generate a new version of this patch soon. Thanks for the catching.
