So users doesn't have internal mic to use. [Fix] Intel provides 2 new topology files to us, they could support 1 dmic and 3 dmics. [Test Case] Boot the kernel with this patch, and put sof-hda-generic-1ch.tplg in the linux-firmware, the sof driver could detect the dmic and users have a workable internal mic after booting up. [Regression Risk] This is adding 2 new topology files, not changing anything on current sof-firmware, so the regression posibility is very low. This is for linux kernel: [Impact] On a Dell tigerlake laptop, the sof driver fails to detect the dmic, it alwasys report 0 dmics on the machine. So users doesn't have internal mic to use. [Fix] Intel write a patch to fix this issue, if NHLT table returns 1 or 3 dmics, the sof driver will not fail like before, it can support 1 or 3 dmics after applying this patch. [Test Case] Boot the kernel with this patch, and put sof-hda-generic-1ch.tplg in the linux-firmware, the sof driver could detect the dmic and users have a workable internal mic after booting up. [Regression Risk] This patch adds new support for 1 and 3 dmics, it doesn't change anything on existing functions, so the regression posibility is very low.
