I have a 4.14 kernel for my i.MX6D/Q using an ov5640 connected in a
similar way as the sabresd and I'm getting similar timeouts.
when executing

media-ctl -l "'ov5640 2-0010':0 -> 'imx6-mipi-csi2':0[1]"
media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"
media-ctl -l "'ipu1_csi1':1 -> 'ipu1_ic_prp':0[1]"
media-ctl -l "'ipu1_ic_prp':1 -> 'ipu1_ic_prpenc':0[1]"
media-ctl -l "'ipu1_ic_prpenc':1 -> 'ipu1_ic_prpenc capture':0[1]"


media-ctl -V "'ov5640 2-0010':0 [fmt:UYVY2X8/640x480 field:none]"
media-ctl -V "'imx6-mipi-csi2':2 [fmt:UYVY2X8/640x480 field:none]"
media-ctl -V "'ipu1_csi1':1 [fmt:AYUV32/640x480 field:none]"
media-ctl -V "'ipu1_ic_prp':1 [fmt:AYUV32/640x480 field:none]"
media-ctl -V "'ipu1_ic_prpenc':1 [fmt:AYUV32/640x480 field:none]"

[ 72.799015] ipu1_ic_prpenc: EOF timeout
[ 73.838985] ipu1_ic_prpenc: wait last EOF timeout

When I try to jump directly to 4.19-RC8, I get errors regarding memory
allocation, so I think there might be something else there I am
missing.

Has anyone tried this camera module on a 4.14 kernel? I noticed there
are a bunch of driver updates, and I was hoping there might be some
patches that could be be backported to the 4.14.y stable branch.

thanks for any suggestions to try.
