That's all fairly standard for this sort of device.  You could still
cope with this by including the I2C address in the default name
requested - do something like tas2562/myboard-addr.fw or whatever.  The
concern here is that someone shouldn't have to replace their DT if they
decide they want to start using the DSP, and someone making a distro
shouldn't be stuck dealing with what happens if multiple vendors decide
to just reuse the same name (eg, just calling everything tas2562
regardless of plastics).
