Within phy.h, an address on an MII bus has been called both addr and
phy_id. phy_id is particularly confusion, since it also means the ID
found in register 3, if the device on the bus is a phy. Consistently
use addr.

These are logically MDIO operations, not phy operations, so move them
into the mdio header.

Since we have a phydev, make use of it and the phy_read() function.
This will help with later refactoring.

Do we have any guarantee that users of this interface do a prior
SIOCGMIIPHY ioctl() to select the PHY address? If not, then this change
forces it. Arguably, you are current allowed to issue MII reads/writes
using a PHY device that can be different from the intent, that does not
sound like a robust interface...

This and the following hunk are wrong, and i will drop them. You are
supposed to be able to read/write any address on the bus, and i
removed this ability.
Thanks for pointing this out.

This should use parentheses around phydev
#define phydev_name(phydev) dev_name(&(phydev)->dev)
or likely even better be a static inline

Removing this gets rid of the bus clocking information that is displayed
here.

It could be nice to expose the format string here along with parameters
to let drivers decide how much additional information they want to print
rather than forcing this to the core PHY library. Maybe something ala
phy_print_status() which takes variadic arguments?
Some drivers also seem to have a netif_msg_probe() conditional to guard
this print, I am not sure if we should keep that, probably not.

Yes, but how useful is that information?
I'm unsure what to do with all these prints. How useful are they? The
information is already in /sys. Are we really interested in seeing
this at boot time?
My main issue with them is that i need to touch them all when moving
members out of phydev into the common mdio device structure. So having
it once in a central place is good.

O.K. that works, since in most cases it will be a call like:
phy_print_attached(phydev);
and sometimes
phy_print_attached(phydev, "mdc_clk=%dHz(mdc_div=%d)@sclk=%dMHz)",
MDC_CLK, mdc_div, sclk/1000000);

Rather than use devm_kzalloc(), use the mdio helper function.

Have mdio_alloc() create the array of interrupt numbers, and
initialize it to POLLING. This is what most MDIO drivers want, so
allowing code to be removed from the drivers.

Yeah, this should have been done a long time ago, thanks!

This looks good to me, I am just wondering if it would make sense to
introduce another patch, prior to this one which does something like:
- expose phydev_addr(phydev) to encapsulate the phy device's addr member
and convert all drivers listed here to that helper, do the same thing
with phydev_bus(phydev) to get the mii_bus of a given PHY device
- have a subsequent patch which relocates phydev->{addr,bus} to the
common MDIO device structure?
Other than that:

We will soon support devices other than phys on the mdio bus. Look at
a child's compatibility string to determine if it is a phy, before
registering a phy device.

Is there a particular reason not to check for
"ethernet-phy-ieee802.3-c22 here?

That seems reasonable, we should probably make the compatible string for
PHY Device Tree nodes not an optional property anymore though, but
that's for a separate change and topic.

Humm interesting. Didn't even know it was a valid compatible string.
Also, Linux does not know it is a valid compatible string:
~/linux$ grep -r "ethernet-phy-ieee802.3-c22" ./drivers
~/linux$
It is however used in a number of DT files and is documented in
Documentation/devicetree/bindings/net/phy.txt.
I will add it here as well.

Yes, printing a warning here would be good.

Rather than have drivers directly manipulate the mii_bus structure,
provide and API for registering and unregistering devices on an MDIO
bus, and performing lookups.

The mdio_bus exports three attributes. However these are all phy
attributes, not generic mdio attributes. So move the attributes into
the phy device code.

It could help to mention why just in case you have to respin that patch
series:
- PHY ID is the unique 32-bits identifier for a MDIO device implementing
standard MII registers MII_PHYSID1/2, which is not guaranteed to be the
case for non-standard compliant devices (e.g: Ethernet switches)
- PHY interface describes the data-path of the PHY/MDIO device, which is
not strictly a PHY thing, but is required and needed for PHY devices to
function, a MDIO device could be a control device exclusively
- PHY has fixups describes what the PHY driver may have done, so
completely PHY specific

When the phy is connected, an info message is printed. If the netdev
it is attached to has not been registered yet, the name
'uninitialised' in the output. By registering the netdev first, then
connecting they phy, we can avoid this.

Humm, I think this should be moved before dsa_slave_phy_setup() because
some of the PHY library calls made in dsa_slave_phy_setup() are starting
the PHY library state machine, so this call here might end up undoing
some of what the library just did. This definitively belongs before the
register_netdev() call though.

The MDIO PM operations are really PHY device PM operations. So move
them into phy_device. This will be needed when we support devices on
the mdio bus which are not PHYs.

To: Florian Fainelli; +Cc: netdev, Andrew Lunn
Rather than have each driver set the driver owner field, do it once in
the core code. This will also help with later changes, when the device
structure will move.

Matching a driver to a device has both generic parts, and parts which
are specific to PHY devices. Move the PHY specific parts into
phy_device.

This function should work with any sort of MDIO device which can be
probed on the bus, not just PHY devices. So generalise it.

Make it clear that mdiobus_scan () will only find devices which have a
vendor/product ID in registers 2 and 3. These are typically PHY
devices. Other sort of MDIO devices, such as switches, are not
expected to be found during the scan.
Similarly, __mdiobus_register(), which calls mdiobus_scan() will only
find PHY devices, and other sorts of MDIO devices are expected to be
instantiated from device tree.

Not all devices on an MDIO bus are PHYs. Meaning not all MDIO drivers
are PHY drivers. Add support for generic MDIO drivers.

Happy new year! Thanks a lot for getting this out both quickly and in an
excellent shape and quality.
Here are few questions that come to mind with the new MDIO device model:
- what kind of API do we need to offer to Ethernet MAC driver? Would
attach/detach and maybe adjust_link be good enough?
- should we consider modeling a MDIO connected switch as a MDIO device
(responding at the pseudo PHY address on the MDIO bus) which then
eventually creates a child MDIO bus and per-port individual PHY devices?
- for MDIO switches with a data-path to an Ethernet MAC (which is
probably 99% of the cases, are there some which do not have such a thing
and are still managed switches?), how much of the existing PHY device
properties (speed, duplex, interface, pause capability) should we think
about moving to the common MDIO device structure? Then this kind of
circles back to the first question about the Ethernet MAC interface API [1]
[1]: One could imagine that the MDIO device with a data-path to an
Ethernet MAC would need at least (RGS)MII knowledge, speed, duplex, and
pause capability, all of that could come from a fixed-link (or similar)
property in DT/platform_data, or as a last resort, the MDIO device
driver, after successful probing could define these parameters.
The Ethernet MAC attaching to that MDIO device would need to be fed with
that information somehow such that we do not have to put too much
knowledge into the MAC driver and still preserve a good layering. Using
something similar to phy_{attach,connect}() (without starting a state
machine here) and phy_{detach,disconnect}() as well as an adjust_link
callback could help minimize the churn on the Ethernet driver side.
Would that seem sensible?
Thanks!

I was not going to offer it any! At least not at the MDIO layer.
Maybe i have DSA too much in mind. But all we need for DSA is probe
and remove. When the MDIO device is probed, based on DT information,
it registers its DSA OPs with the DSA framework. When the device is
removed, it unregisters its DSA ops. Nothing else is needed.
Also, don't forget you can have an MDIO bus without an MII bus. The
classic examples are using a couple of gpio lines to bit bang, or
using a mux to give you multiple MDIO busses from one real MDIO bus
and some gpio pins.

Sort of. The Marvell switch actually take up quite a few addresses on
the MDIO bus, not just the one listed in the DT. By convention, if the
address is zero, the switch is assumed to be in single chip mode, and
will respond to 10 or more different addresses. Depending on the
switch model, some of those addresses are actually phys, and should be
listed in DT as phys.
If the address is not zero, the switch is in multi-chip mode, and it
will respond to registers 0x00 and 0x01 on that one address. These two
registers give an indirect access to all the other registers.

To me, MII and MDIO are separate busses and should not be mixed
together. Think about the case of a switch with two MII busses for
greater frame throughput, but only one MDIO bus for management? Some
of the Marvell switches can also be manged using messages in Ethernet
frames. So you could even have a switch with only MII and no MDIO!
What also comes to play here is Russell Kings phylink code.
We have this 20+ part patchset. This gives us enough we can look at
integrating the 20+ part DSA probing patchset and then look at RMKs
20+ patchset. That alone should keep us busy for a while without
needed to add yet more.
