I don't think so. The fim child node does not represent a device. The
CSI supports monitoring frame intervals (reporting via a v4l2 event
when a measured frame interval falls outside the nominal interval
by some tolerance value). The fim child node is only to group properties
for the FIM under a common child node.

Done.
