That sounds about right. If there is interest I can sift through my mail
archive and see if it yields any answers.

Thanks, I have marked this and the following patch as deferred.
Please repost or otherwise ping me once the dependencies are in place.

Apparently CONFIG_VIDEO_SH_MOBILE_CEU was set in the old
armadillo800eva_defconfig, and used by the old board code.
While DT bindings do exist [1], some DT support has been added to the
driver [2], and this even ended up as the example in [3], this was never
enabled in the corresponding board DTS.
Nevertheless, I understand that soc_camera-based driver is obsolete, and
has been replaced by [4], but bindings for r8a7740 are lacking [5].
