Hello, adi,
   I have a questions about adv7180 hsync.adv7180 ouput HS frequency is 15.6 KHZ, but HS pulse width only dozens of ns, not the standard of 4.7 us. I set the register to make adv7180 work in free run mode and the output HS pulse width only dozens of ns too. ADV7180 registers set according to the configuration of detasheet table 105.
