grep -Er . /sys/devices/pnp0/00\:01/* 2>/dev/null
/sys/devices/pnp0/00:01/firmware_node/hid:PNP0C02
...

so this PNP0C02 is 

[    0.363943] system 00:01: Plug and Play ACPI device, IDs PNP0c02 (active)

@Rafael, can you please make sense of this whole ACPI gunk?

We have a resource conflict with pnp 00:01, analysis here:
