I think it can be said based on debian build logs. Lemme see..

https://buildd.debian.org/status/logs.php?pkg=qemu&arch=all

The first log entry there is from 2018-12-12, for qemu 3.1, dtc 1.4.7.
It has:

dtc -o b/qemu/pc-bios/bamboo.dtb pc-bios/bamboo.dts
b/qemu/pc-bios/bamboo.dtb: Warning (unit_address_vs_reg): /memory: node has a 
reg or ranges property, but no unit name
b/qemu/pc-bios/bamboo.dtb: Warning (unit_address_vs_reg): /plb/opb: node has a 
reg or ranges property, but no unit name
b/qemu/pc-bios/bamboo.dtb: Warning (chosen_node_stdout_path): 
/chosen:linux,stdout-path: Use 'stdout-path' instead
b/qemu/pc-bios/bamboo.dtb: Warning (interrupts_property): /plb/opb: Missing 
interrupt-parent
b/qemu/pc-bios/bamboo.dtb: Warning (interrupts_property): /plb/opb/ebc: Missing 
interrupt-parent

next it was moved to one of the subpackages, and moved back to
arch-independent package in 6.2 (2022-01-09, dtc 1.6.0), which has:

dtc -o b/misc/bamboo.dtb pc-bios/bamboo.dts

FWIW.
