Hello Arnd,
I'm sorry to inform you that commit
a0f480dc6546b9d97027bf7bc8145aad48ddad00 causes a regression in
5.15-rc1 for the meson-dwmac8b ethernet driver.
meson-dwmac8b never loads and libphy never probes stmmac
I've bisected it over the weekend. The results follow.
The bad commit mostly consists of qcom DT changes that shouldn't
trigger anything nasty like missing ethernet for meson (amlogic) but
there's the possibility the regression is caused by stmmac
modifications inside "Merge tag 'v5.14-rc3' into arm64-for-5.15
(2021-08-16 18:02:26 -0500)"
This is just a guess as I haven't been able to pinpoint so far what
precisely causes the regression.
Best,
Geraldo Nascimento

Qualcomm ARM64 updates for v5.15
SDM660 and SDM630 was concluded to be similar enough that they should be
merged, and the derivative SDM636 was added to the bunch. The combined
platform gained support for GPU, DMA, I2C, IMEM, display, power-domains,
SDHCI, thermal, USB, interconnects, VADC, WLED and audio remoteproc. The
Sony Xperia "Ganges" platform was similarly merged with "Nile", got
cleaned up and gained touchscreen, USB, volume keys and uSD support.
IPQ6018 gains USB2 and PCIe support and a few minor fixes. IPQ8074
gains SCM, PRNG and Crypto support and a DT style update of the PCIe
nodes.
MSM8916 gains Coresight STM support. The Xiaomi Redmi 2 is introduced,
with touchscreen, notification LED and IMU support. MSM8996 gains
support for GPU cooling and v3.0 of the SoC, which is used to introduce
support for the Sony Xperia X Performance, XZ and XZs phones.
SC7180 finally gains DisplayPort support and LPASS is updated
accordingly. A number of fixes are introduced and with the newly
introduced DRM aux bus in place Trogdor's panel is moved under the eDP
bridge. SC7280 gained USB, eMMC, SD-card, QFPROM and IPA support, the
new IDP2 board was added.
SM6126 (aka Snapdragon 665) was introduced, together with the Sony
Xperia 10II phone with support for framebuffer, USB, eMMC and volume
keys.
SM8150 gained inline crypto support for UFS enabled, CPU opp-tables was
introduced to scale DDR and L3 frequencies and SPI nodes where added, in
addition to a number of smaller fixes.
SM8250 gained a number of minor fixes and had its serial engines wired
up to use the GENI wrappers' DMA engines.
SM8350 had wakeup-parent defined for the TLMM gpio node and I2C13 was
introduced.
SDM845 display clocks was corrected and Lenovo Yoga C630 got IPA enabled
and now has working LTE connectivity.
Additionally a number of minor fixes throughout to correct DT validation
warnings.
Lastly v5.14-rc3 is merge in to resolve the merge conflicts caused by
the USB maintainer deciding to fix a regression in his tree.

Which board/SoC are you referring to?
I can confirm that dwmac-meson8b still works fine on an Odroid-C1
(Meson8b SoC) with 5.15-rc2
Newer (arm64) SoCs additionally use an MDIO mux driver:
- mdio-mux-mmioreg on GXL, GXM
- mdio-mux-meson-g12a on G12A, G12B, SM1
Best regards,
Martin

Indeed it's an issue with mdio muxes, a similar issue had been reported by Marek at https://lore.kernel.org/all/0a2c4106-7f48-2bb5-048e-8c001a7c3fda@samsung.com/
and it concerns commit cf4b94c8530d ("of: property: fw_devlink: Add support for "phy-handle" property")
It may be the same issue here.

At least for me the issue is gone in 5.15-rc2 and present only in 5.15-rc1
My board is is based on the q200 reference design, with 1 GbE external phy.
The only difference between my board and the q200 reference AFAIK is
an Atheros Qualcomm WiFi / BT chip, QCA9377 but this is unrelated.
It's a TV Box branded as H96 Pro+

Whatever it was, it seems to be gone at least for me in 5.15-rc2 so it
seems to be low priority unless it reappears.

I'm sure it's not this commit, looking at the contents of the tree
before and after,
it does not touch a single file that is used on your machine.
Sometimes bisections are unreliable. I would suggest you re-test commit
a0f480dc6546b9 and the one before it, one of them will likely show a different
result from what you had. You can then replay your bisection to find
the actual cause.

Thanks, Arnd, I was a bit puzzled to say the least because that commit
seemed totally unrelated like you state yourself.
Like I have mentioned in my other email in reply to Neil and Martin,
issue seems to be gone at least for me in 5.15-rc2.
So unless it reappears I think there's little to do.
Thanks,
Geraldo Nascimento
