I did but it does not make a difference.

Changed this as well. What I do now is the following:
SF="UYVY2X8"
IF="AYUV32"
GEOM="1280x1024"
media-ctl -r
media-ctl -l "'mt9m111 2-0048':0 -> 'ipu1_csi0_mux':4[1]"
media-ctl -l "'ipu1_csi0_mux':5 -> 'ipu1_csi0':0[1]"
media-ctl -l "'ipu1_csi0':2 -> 'ipu1_csi0 capture':0[1]"
media-ctl -d /dev/media0 -v -V "'mt9m111 2-0048':0 [fmt:${SF}/${GEOM} field: none]"
media-ctl -d /dev/media0 -v -V "'ipu1_csi0_mux':4 [fmt:${SF}/${GEOM} field: none]"
media-ctl -d /dev/media0 -v -V "'ipu1_csi0_mux':5 [fmt:${SF}/${GEOM} field: none]"
media-ctl -d /dev/media0 -v -V "'ipu1_csi0':2 [fmt:${IF}/${GEOM} field:none]"

I will take a look at the sensor configuration. Maybe there is some issue or a
difference among all th MT9M1x1 semsors the driver does not support.

I uploaded the complete topology output from media-ctrl -p as well [1].
