We have imx8qxp Soc with the off-chip hdmi converter (sii9022a). I'm trying to get picture using ELCDIF DVI mode ( i think problem is in embedded sync signal settins which is not yet clear for me.

The question is: is it possible to get external hsync/vsync along with BT.656 DVI/YCbCr 4:2:2 color space  mode (LCDIF_VDCTRL4[18] = 1 and LCDIFCTRLn[20] = 1)?

Thanks in advance.
