For those platforms, the SOF or SST drivers need to be used. This patch provides an automatic way of detecting the presence of DMICs using NHTL information reported by the BIOS. A kernel kconfig option or a kernel module parameter provide an opt-in means of stopping the probe. The kernel would then look for an alternate driver registered for the same PCI ID to probe. With this capability, distros no longer have to blacklist snd-hda-intel, but still need to make sure the SOF/SST drivers are functional by providing the relevant firmware and topology files in /lib/firmware/intel The coexistence between SOF and SST drivers and their dynamic detection is not addressed by this patch, different mechanisms need to be used, e.g. DMI-based quirks.
