This direction seems slightly problematic, especially in the

if that is wrong). It would probably be better to be fixing
things up such that the amp in question sets system_name when

I also consider setting system_name when registered by DT, but I don't
known setting what name to it. Card name or something else?
It just has to be a unique string.
The normal process is that Cirrus would release the firmware with the
correct name for the platform, so the system-name matches the string in
those release firmware files.
Do you have an official firmware for your platform?
tuning is going to be specific to the enclosure/speaker involved,
so a generic tuning for say left amps doesn't really make a lot
of sense.
I don't known about amp tuning much, my need just is loading firmware for
more than 1 speaker amp at the platform using fdt.
One of the both way is good to me.
Thanks,
