** Description changed:
[Impact]
Systems using Intel SoundWire codecs from the tac5xx2 family on Intel NVL may
fail to wake from suspend. The codec was not treated as a wake-capable device.
Symptom: system does not resume with normal wake inputs and dmesg shows no
SoundWire wake/resume messages.
[Fix]
+ ====== linux kernel ======
Add tac5xx2 family to the intel_auxdevice wake_capable_list so the codec is
recognized as wake-capable. Upstream commit: 1d4d3198ccce. No released v* tag
contains this commit (appears in the upstream tree).
+
+ ====== firmware-sof ======
+ https://github.com/thesofproject/sof-bin/releases/tag/v2026.09
[Test Plan]
Suspend and wake 10 times:
$ sudo rtcwake -m mem -s 20
Use the usual wake input (power button, lid, keyboard).
Without patch: system fails to resume or needs manual power. With patch:
system resumes normally and dmesg shows SoundWire wake/resume messages.
[Where problems could occur]
If a non-wake-capable device is added, machines may see immediate wakeups or
fail to enter deep suspend. This would show as repeated spurious wakes or
inability to reach low-power suspend while running the intel_auxdevice
SoundWire driver.
[Other Info]
Subsystem: drivers/soundwire (intel_auxdevice). Target: mainline and
backports for Ubuntu kernels as needed.
** Also affects: firmware-sof (Ubuntu)
