would be nice if

ld: drivers/soc/adi/system.o: in function `system_config_probe':
system.c:(.text+0x416): undefined reference to `__devm_regmap_init_mmio_clk'

I believe it depends on it but doesn't depends on the kconfig

I'll try to deal with it in a new PR, but the issue is that the code is not conditionalized. There is no drivers/soc/adi/Kconfig and the Makefile just obj-y += system.o. As I recall this was something that mainline didn't like. Need to dig into how Arturs dealt with it in his series, but even if it does fix it that has been applied to adsp-6.12.38-y.
