can't really say if that is the issue in this case, but these are the symptoms you'd see if the kernel was built without some driver that imx-drm depends on[1]. The kernel will only try to reprobe a driver if some other driver has loaded since it last deferred (otherwise, it would be pointless, you'd just -EPROBE_DEFER again). [1] which is a really annoying thing about devicetree.. there's no good way to figure out which drivers need to be enabled in kernel config..
