I don't know what minimal image dimensions are, but 32x32 appears to
be ok according to the docs.
This is needed for small sensors like 80x80 thermal imagers.

This looks fine to me for the CSI. Steve, are you aware of any
limitations?
I looked at the imx6 ref manual and don't see any limitations in IC or
VDIC or IDMAC or CPMEM, so this is fine to me as well.
One nitpick, please change the all-caps commit subject to
media: imx: Remove unneeded geometry restrictions from i.MX CSI driver
After that,

(with CSI crop to 32x32, I have no 32x32 sensors at hand)
