i2c4 shares pins with vin0. Hence enabling the former breaks the latter:

    sh-pfc e6060000.pfc: pin GP_4_13 already requested by
e6520000.i2c; cannot claim for e6ef0000.video
    sh-pfc e6060000.pfc: pin-141 (e6ef0000.video) status -22
    sh-pfc e6060000.pfc: could not request pin 141 (GP_4_13) from
group vin0_data24  on device sh-pfc
    rcar-vin e6ef0000.video: Error applying setting, reverse things back
    rcar-vin: probe of e6ef0000.video failed with error -22

There may be similar issues on other boards. Haven't checked yet.

Thanks, I will drop this patch for now.

I checked the boot logs of other boards with similar patches and didn't see
anything there.

Do you have CONFIG_VIDEO_ADV7604=y?

No, mainly because its not in shmobile_defconfig.

I tried again with that option enabled and still didn't see
anything of interest in kernel log.

I expect the issue to be present on gose, too. So far I didn't see it
there, yet.
But the vin DTS of gose is different from koelsch, causing vin0 not to be
initialized?

It seems so.
