Hi Tim,

I gave this a shot a while ago, but I recall struggling with some 
locking problems. I haven't been able to return to it. I've updated the 
imx/add-fim-to-prpencvf branch to latest media-tree master branch 
(5.11.0-rc1), in my github fork [1]. The patches against master are:

0001-media-imx.rst-update-doc-to-reflect-FIM-changes.patch
0002-media-imx-prpencvf-attach-FIM.patch
0003-WIP.patch

The last patch was my first attempts to debug the locking problems.

I don't have access to imx6 hardware any longer, so I can't progress any 
further on it at this point.

Steve,

Some time ago you mentioned that adding FIM capability
(imx-media-fim.c) on the ipu{1,2}_ic_prp{enc,vf} capture nodes was on
your plate to fix as currently the controls are only available on the
ipu{1,2}_csi{0,1} capture nodes. Do you have any patches for that or
can you explain what needs to be done?

I have a user that wishes to use FIM to deal with a lossy analog
signal coming out of sync but they also wish to use the VDIC to
de-interlace.

Best regards,

Tim
