Raspberry Pi Camera V2.1

hi guys,
i'm having a look at this. apparently there's something preventing the boot image to run properly with the 2.1 camera. actually i had a look at the (reverse engineered) schematics of the camera and it looks like a pin that was previously input is now an output so also the vidorgraphics image will need to be updated.
i tried that on my side and regardless the update and some changes to the init struct to reflect 8 bit rather than 10 i don't get any picture. in order for vidor to work we have to lower pixel frequency at something below 50 MHz so i changed register 0x307 to 0x14 and 0x30d to 0x28 which should be fune but it doesn't seem to work.
any suggestions from who already used this sensor?
thanks,

Dario
