Dear Kernel maintainers,
I think i'm encountering (for the first time in years !) a regression
with the "6.7.arch3-1" kernel (whereas no issues with
"6.6.10.arch1-1", on which i reverted).
I'm running a (up-to-date, and non-LTS) ARCHLINUX desktop, on a ASUS
B560-I motherboard, with 3 monitors (attached to a 4-HDMI outputs
card), plus an audio S/PDIF optic output at motherboard level.
With the latest kernel, the S/PIDF optic output of the motherboard is
NOT detected anymore (and i haven't been able to see / find anything
in the logs at quick glance, neither journalctl -xe nor dmesg).
Once reverted to 6.6.10, everything is fine again.
For example, in a working situation (6.6.10), i have :
cat /proc/asound/pcm
00-00: ALC1220 Analog : ALC1220 Analog : playback 1 : capture 1
00-01: ALC1220 Digital : ALC1220 Digital : playback 1
00-02: ALC1220 Alt Analog : ALC1220 Alt Analog : capture 1
01-03: HDMI 0 : HDMI 0 : playback 1
01-07: HDMI 1 : HDMI 1 : playback 1
01-08: HDMI 2 : HDMI 2 : playback 1
01-09: HDMI 3 : HDMI 3 : playback 1
Whereas while on the latest 6.7 kernel, i only had the 4 HDMI lines
(linked to a NVIDIA T600 card, with 4 HDMI outputs) and not the three
first ones (attached to the motherboard).
(of course i did several tests with 6.7, reboot, ... without any changes)
Any idea ?
Best regards

On SoCFPGA/Sodia board, mdio bus cannot be probed, so the PHY cannot be
found and the network device does not work.
```
stmmaceth ff702000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19)
```
To probe the mdio bus, add "snps,dwmac-mdio" as compatible string of the
mdio bus. Also the PHY address connected to this board is 4. Therefore,
change to 4.
