Bug description:
[Impact]
There is no sound cards on Intel LNL platform of ThinkPad TM2.
[Fix]
Add soc-acpi table entry on LNL for ThinkPad TME laptop
with rt713 and rt718.
This kernel patch depends on new sof firmware:
db771bf v2.11.x: add new 2.11.2 topology2 production binaries
665e39d Add SOF v2.11.1 signed Intel binaries for MTL/LNL/ARL
The sof-firmware will be SRU in bug 2086250
[Test]
Tested on hardware, audio input and output can work
with the patch and new sof-firmware.
$ cat /proc/asound/cards
0 [sofsoundwire ]: sof-soundwire - sof-soundwire
LENOVO-21NTZCF5CN-ThinkPadX1CarbonGen13
$ speaker-test -c 2
$ arecord -f cd cd.wav
[Where problems could occur]
It may break audio on Intel LNL platform.
The commit is from 6.12 kernel;
LNL is only supported on 6.11+ kernel;
So SRU for oem-6.11 and oracular only.
