Bug description:
This is for linux-firmware:
[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 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.
