hello akrupnik,

there’s device tree setting, lane_polarity to configure a polarity swap.
it’s mentioned in reference device tree.
for example, $public_sources/kernel_src/hardware/nvidia/platform/t23x/p3768/kernel-dts/cvb/tegra234-camera-rbpcv2-imx219.dtsi

                                * lane_polarity
                                * Based on the camera connector pin.
                                * CSIx_D0 | CSIx_D1 | CSI(X+1)_D0 | CSI(X+1)CSIx_D1
                                *    LSB  |   BIT1  |     BIT2    |      MSB
                                * if there is a polarity swap on any lane, the bit corrsponding
                                * to the lane should be set
                                * e.g. polarity swap on CSIx_D0 only -> lane_polarity = "1"; 0001
                                * e.g. polarity swap on CSIx_D1 and CSI(X+1)_D0 -> lane_polarity = "6"; 0110
