** Description changed:
- This bug is for tracking purpose
+ Because we plan to remove sof-firmware related files from linux-firmware
+ of jammy and replace them with a debian package firmware-sof-signed, so
+ this SRU is not applied to jammy. I will submit another SRU to
+ firmware-sof-signed package later.
+
+ [Impact]
+ In the Dell oem project, we have many laptops which has sof dmic or
+ sof soundwire audio design, they need to load firmware and topology
+ files specific to ADL, otherwise the audio driver will fail to
+ initialize and the whole audio can't work.
+
+ [Fix]
+ Integrate the firmware and topology files from sof-firmware-v1.9.2
+
+ [Test]
+ Installed the patched linux-firmware and booting the patched kernel,
+ the audio work well, all output and input devices work normally
+
+ [Where problems could occur]
+ This SRU introduces new firmware and topology files for adl, it has
+ low possibility to introduce regression. If it could, it could
+ possibilily affect the other machines which also need to load firmware
+ and topology files, it could make the audio can't work on those machines,
+ but this possibility is very low, we have tested the SRU on many laptops,
+ no regression found.

[Impact]
In the Dell oem project, we have many laptops which has sof dmic or
sof soundwire audio design, they need to load firmware and topology
files specific to ADL, otherwise the audio driver will fail to
initialize and the whole audio can't work.
[Fix]
Integrate the firmware and topology files from sof-firmware-v1.9.2
[Test]
Installed the patched linux-firmware and booting the patched kernel,
the audio work well, all output and input devices work normally
[Where problems could occur]
This SRU introduces new firmware and topology files for adl, it has
low possibility to introduce regression. If it could, it could
possibilily affect the other machines which also need to load firmware
and topology files, it could make the audio can't work on those machines,
but this possibility is very low, we have tested the SRU on many laptops,
no regression found.
