I guess this is in use already and okay. However, looking at the driver there really should be SoC specific compatible strings here since the driver is looking up the SoC compatible string and composing the firmware filename from that.

Drop device_type. It should only be used in a few legacy cases.
Looks like the driver is matching on this. Please drop it from the driver too. I'd leave dts files for now, but they should be updated too later.
