I have an observation that's slightly out of the scope of your patch,
but I'll post here on the off chance that you find it relevant.
Apologies if it's out of place.

Do these integrated NXP PHYs use a specific PHY driver, or do they just
use the Generic PHY driver?

They refuse to probe at all with the Generic PHY driver. I have been
caught off guard a few times now when I had a kernel built with
CONFIG_NXP_C45_TJA11XX_PHY=n and their probing returns -22 in that case.

If the former is the case, do you experience that the PHY driver fails
to get probed during mdiobus registration if the kernel uses
fw_devlink=on?

I don't test with "fw_devlink=on" in /proc/cmdline, this is the first
time I do it. It behaves exactly as you say.

Sorry for the delay, I wanted to reconfirm what I said (hint, I was wrong).

In my case, whatever I do, I cannot get the driver core enforce a device
link between the ethernet-switch and the PHY.

So I cannot actually see the same issue. What I was seeing was in fact
stupid testing on my part (it was working with the PHY driver as
built-in, it was working, then I made it a module, it broke, I forgot to
switch it back to module, then I thought it's broken while the PHY is
built-in).

In my case I am writing a new subdriver for realtek-smi, a DSA driver
which registers an internal MDIO bus analogously to sja1105, which is
why I'm asking. I noticed a deferred probe of the PHY driver because the
supplier (ethernet-switch) is not ready - presumably because all of this
is happening in the probe of the switch driver. See below:

So it's a circular dependency? Switch cannot finish probing because it
cannot connect to PHY, which cannot probe because switch has not
finished probing, which....

Hi Vladimir/Alvin,

If there's a cyclic dependency between two devices, then fw_devlink=on
is smart enough to notice that. Once it notices a cycle, it knows that
it can't tell which one is the real dependency and which one is the
false dependency and so stops enforcing ordering between the devices
in the cycle.

But fw_devlink doesn't understand all the properties yet. Just most of
them and I'm always trying to add more. So when it only understands
the property that's causing the false dependency but not the property
that causes the real dependency, it can cause issues like this where
fw_devlink=on enforces the false dependency and the driver/code
enforces the real dependency. These are generally easy to fix -- you
just need to teach fw_devlink how to parse more properties.

This is just a preliminary analysis since I don't have all the info
yet -- so I could be wrong. With that said, I happened to be working
on adding fw_devlink support for phy-handle property and I think it
should fix your issue with fw_devlink=on. Can you give [1] a shot?

I tried [1] but it did not seem to have any effect.

I applied the phy-handle patch, and here are my boot logs.

As you can see, there was no provider/consumer relationship enforced
between the PHY at spi1.0-base-t1\:01 and the ethernet-switch.

If it doesn't fix it, can one of you please point me to an upstream
dts (not dtsi) file for a platform in which you see this issue? And
ideally also the DT nodes and their drivers that are involved in this
cycle? With that info, I should be able to root cause this if the
patch above doesn't already fix it.

I'm working with a non-upstream dts - maybe Vladimir is using an
upstream one? The pattern among the drivers/dts is common between our
two cases.

Ideally, I can get a fully upstream example where this issue is
happening so that I can look at the actual code that's hitting this
issue and be sure my analysis is right.

Mine isn't upstream either, but I have no issue sharing it with you.

2. The child devices could defer probe because one of their suppliers
isn't ready yet. Either because of fw_devlink=on or the framework
itself returning -EPROBE_DEFER.
3. The child devices could be getting probed asynchronously. So the
device_add() would kick off a thread to probe the child devices in a
separate thread.

(2) is what is happening in this case. fw_devlink=on sees that
"switch" implements the "switch_intc" and "switch" hasn't finished
probing yet. So it has no way of knowing that switch_intc is actually
ready. And even if switch_intc was registered as part of switch's
probe() by the time the PHYs are added, switch_intc could get
deregistered if the probe fails at a later point. So until probe()
returns 0, fw_devlink can't be fully sure the supplier (switch_intc)
is ready. Which is good in general because you won't have to
forcefully unbind (if that is even handled correctly in the first
place) the consumers of a device if it fails probe() half way through
registering a few services.
