[Sound-open-firmware] SOF in a laptop Whiskey Lake ALC215

[josep lladonosa capell]

I add that ACPI has an NHLT table:

$ dmesg | grep NHLT
[    0.016203] ACPI: NHLT 0x00000000B3BC3000 0017F1 (v00 INTEL
CFL-ULT  20170001 INTL 20160422)

But (related to snd-hda-intel, though):
sound/hda/intel-nhlt.c:33 [snd_intel_dspcfg]intel_nhlt_init =p "No
NHLT table found\012"

$ sudo acpidump | grep NHLT
NHLT @ 0x0000000000000000
    0000: 4E 48 4C 54 F1 17 00 00 00 17 49 4E 54 45 4C 20  NHLT......INTEL
   10AA0: 6E 20 31 20 4E 48 4C 54 00 A4 4E 42 55 46 A1 4B  n 1 NHLT..NBUF.K

Attached you will find nhlt.dsl file.
