Typically the hardware configuration for I2S and DMIC devices resides in the Non-HDAudio Link Table (NHLT) that is part of the ACPI tree. As the NHLTs existing in the field are not always perfect, workaround mechanisms are provided to patch them. Currently the avs-driver is utilizing the ->blob_fmt override (see topology.h and struct avs_tplg_modcfg_ext) when there is a valid entry within a NHLT to configure the hardware for specific format but its descriptor (header) is invalid. A separate case is when there is no correct hardware configuration at all within the NHLT available in the system. Patching the header won't help and forcing ad-hoc BIOS updates for dated system is not feasible. Allowing the topology to carry the data is the solution of choice as replacing a userspace file that is part of /lib/firmware/intel/ is less invasive than BIOS update and solves the problem.
