In devlink, some of the objects have separate ops registered alongside
with the object itself. Port however have ops in devlink_ops structure.
For drivers what register multiple kinds of ports with different ops
this is not convenient. Introduce devlink_port_ops and a set
of functions that allow drivers to pass ops pointer during
port registration.

Add support for the Microchip LAN865x Rev.B0 10BASE-T1S Internal PHYs
(LAN8650/1). The LAN865x combines a Media Access Controller (MAC) and an
internal 10BASE-T1S Ethernet PHY to access 10BASE‑T1S networks. As
LAN867X and LAN865X are using the same function for the read_status,
rename the function as lan86xx_read_status.

The only place where this variable would be set to false is the

for (i = 0; i < dev->phy_port_cnt; i++) {
if (i == dev->phy_port_cnt) <--- will be never executed.
break;
p->on = 1;
So, we never have a situation where p->on = 0. In this case, we can just

It is not immediately obvious that this driver allocates, via the
KSZ_REGMAP_TABLE() macro, 3 regmaps for register access: dev->regmap[0]
for 8-bit access, dev->regmap[1] for 16-bit and dev->regmap[2] for
32-bit access.
In future changes that add support for reg_fields, each field will have
to specify through which of the 3 regmaps it's going to go. Add an enum
now, to denote one of the 3 register access widths, and make the code go
through some wrapper functions for easier review and further
modification.

This patch refines the error handling mechanism for 8-bit register
read-modify-write operations. In case of a failure, it now logs an error
message detailing the problematic offset. This enhancement aids in
debugging by providing more precise information when these operations
encounter issues.
Furthermore, the ksz_prmw8() function has been updated to return error
values rather than void, enabling calling functions to appropriately
respond to errors.
Additionally, in case of an error that affects both the current and
future accesses, the PHY driver will log the errors consistently, akin
to the existing behavior in all ksz_read*/ksz_write* helpers.

====================
net: pcs: add helpers to xpcs and lynx to manage mdiodev
This morning, we have had two instances where the destruction of the
MDIO device associated with XPCS and Lynx has been wrong. Rather than
allowing this pattern of errors to continue, let's make it easier for
driver authors to get this right by adding a helper.
The changes are essentially:
1. Add two new mdio device helpers to manage the underlying struct
device reference count. Note that the existing mdio_device_free()
doesn't actually free anything, it merely puts the reference count.
2. Make the existing _create() and _destroy() PCS driver methods
increment and decrement this refcount using these helpers. This
results in no overall change, although drivers may hang on to
the mdio device for a few cycles longer.
3. Add _create_mdiodev() which creates the mdio device before calling
the existing _create() method. Once the _create() method has
returned, we put the reference count on the mdio device.
If _create() was successful, then the reference count taken there
will "hold" the mdio device for the lifetime of the PCS (in other
words, until _destroy() is called.) However, if _create() failed,
then dropping the refcount at this point will free the mdio device.
This is the exact behaviour we desire.
4. Convert users that create a mdio device and then call the PCS's
_create() method over to the new _create_mdiodev() method, and
simplify the cleanup.
We also have DPAA2 and fmem_memac that look up their PCS rather than
creating it. These could also drop their reference count on the MDIO
device immediately after calling lynx_pcs_create(), which would then
mean we wouldn't need lynx_get_mdio_device() and the associated
complexity to put the device in dpaa2_pcs_destroy() and pcs_put().
Note that DPAA2 bypasses the mdio device's abstractions by calling
put_device() directly.

In order to have our interrupt descriptor fully setup and in particular
the action, ensure that we register a full fledged interrupt handler.
This also allow us to set the interrupt polarity and flow through the
same call.
This is specifically necessary for kernel/irq/pm.c::suspend_device_irq
to set the interrupt descriptor to the IRQD_WAKEUP_ARMED state and
enable the interrupt for wake-up since it was still in a disabled state.
Without an interrupt descriptor we would have ran into cases where the
wake-up interrupt is not capable of waking up the system, specifically
if we resumed the system ACPI S5 using the Ethernet PHY. In that case
the Ethernet PHY interrupt would be pending by the time the kernel
booted, which it would acknowledge but then we could never use it as
a wake-up source again.
