According to part "Table 66. Camera Input Signal Cross Reference, Format, and Bits Per Cycle" in IMX6DQPAEC.pdf
BT.656 data should be feed in IPUx_CSIx_DATA[19:12].
But in my application, i need at least one BT.656 port input, one BT.1120 port input and at least 3 UARTS. most of UARTS share pins on IPUx_CSIx_DATA[19:12]. So i want to use IPUx_CSIx_DATA[9:2] to capture BT.656. Does it make sense by changing software?
