Is there a command for printing the device tree on a running system? I
want to see what changes the various device drivers made to the DTC I
started with.

It's exported in /proc/device-tree, if support is built into the kernel.

That worked, didn't know the option existed.

It might be interesting to make dtc support turning that into a dts...

dtc does support that.  Pass /proc/device-tree/ to dtc like this:

dtc -I fs -o device-tree.dts -O dts /proc/device-tree
