[PATCH] Asoc: wm_adsp: Add support for loading firmware with prefix name

[Jianhua Lu]

For platform using fdt, system_name is NULL, it doesn't provide
a way to load firmware with prefix name, so add it.

This direction seems slightly problematic, especially in the
context of amps (which I presume this relates to, please let know
if that is wrong). It would probably be better to be fixing
things up such that the amp in question sets system_name when
registered through DT. Generally speaking the idea is the amp
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.

Thanks,
Charles

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?

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.

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?

My device is Xiaomi Pad 5 Pro, vendor releases wmfw firmware with
default name, coeff firmware with prefix name(TL, TR and BL, BR....),
don't contain a unique string in firmware name.

This is intended behavior.

To load per-amp tuning you must know the function of each amp.
You only know that if you know what hardware platform you are running
on.

So if system_name is NULL it should fall back to generic firmware.

Make sense
