xgene_mdio_status is declared static, and is only written once by the
driver. It appears to have been this way since the driver was first
added to the kernel tree. No other users can be found, so let's remove
it.

Based on the original code semantic in case of Clause 45 MDIO, the address
command is supposed to be followed by the command sending the MMD address,
not the CSR address. The commit 002dd3de097c ("net: mdio: mdio-bitbang:
Separate C22 and C45 transactions") has erroneously broken that. So most
likely due to an unfortunate variable name it switched the code to sending
the CSR address. In our case it caused the protocol malfunction so the
read operation always failed with the turnaround bit always been driven to
one by PHY instead of zero. Fix that by getting back the correct
behaviour: sending MMD address command right after the regular address
command.

When building with clang 18 I see the following warning:
| drivers/net/mdio/mdio-xgene.c:338:13: warning: cast to smaller integer
| type 'enum xgene_mdio_id' from 'const void *' [-Wvoid-pointer-to-enum-cast]
| 338 | mdio_id = (enum xgene_mdio_id)of_id->data;
This is due to the fact that `of_id->data` is a void* while `enum
xgene_mdio_id` has the size of an int. This leads to truncation and
possible data loss.

There exists several examples today of devices that embed an ethernet
PHY or PCS directly inside an SoC. In this situation, either the device
is controlled through a vendor-specific register set, or sometimes
exposes the standard 802.3 registers that are typically accessed over
MDIO.
As phylib and phylink are designed to use mdiodevices, this driver
allows creating a virtual MDIO bus, that translates mdiodev register
accesses to regmap accesses.
The reason we use regmap is because there are at least 3 such devices
known today, 2 of them are Altera TSE PCS's, memory-mapped, exposed
with a 4-byte stride in stmmac's dwmac-socfpga variant, and a 2-byte
stride in altera-tse. The other one (nxp,sja1110-base-tx-mdio) is
exposed over SPI.

Commit 87e3bee0f247 ("net: mdio: i2c: Separate C22 and C45 transactions")
separated the non-rollball bus accessors, but left the rollball
accessors as is. As rollball accessors are clause 45, this results
in the rollball protocol being completely non-functional. Fix this.

During the refactoring in the commit below, vsc9953_mdio_read() was
replaced with mscc_miim_read(), which has one extra step: it checks for
the MSCC_MIIM_DATA_ERROR bits before returning the result.
On T1040RDB, there are 8 QSGMII PCSes belonging to the switch, and they
are organized in 2 groups. First group responds to MDIO addresses 4-7
because QSGMIIACR1[MDEV_PORT] is 1, and the second group responds to
MDIO addresses 8-11 because QSGMIIBCR1[MDEV_PORT] is 2. I have double
checked that these values are correctly set in the SERDES, as well as
PCCR1[QSGMA_CFG] and PCCR1[QSGMB_CFG] are both 0b01.

As can be seen, the data in MIIM_DATA is still valid despite having the
MSCC_MIIM_DATA_ERROR bits set. The driver as introduced in commit
84705fc16552 ("net: dsa: felix: introduce support for Seville VSC9953
switch") was ignoring these bits, perhaps deliberately (although
unbeknownst to me).
This is an old IP and the hardware team cannot seem to be able to help
me track down a plausible reason for these failures. I'll keep
investigating, but in the meantime, this is a direct regression which
must be restored to a working state.
The only thing I can do is keep ignoring the errors as before.

Since that, in mdio_device_release(), it needs to call
fwnode_handle_put() in addition instead of calling kfree()
directly.
After above, just calling mdio_device_free() in the error handle
path of of_mdiobus_register_device() is enough to keep the

make it easier to extend this function.

Some multigig SFPs from RollBall and Hilink do not expose functional
MDIO access to the internal PHY of the SFP via I2C address 0x56
(although there seems to be read-only clause 22 access on this address).
Instead these SFPs PHY can be accessed via I2C via the SFP Enhanced
Digital Diagnostic Interface - I2C address 0x51. The SFP_PAGE has to be
selected to 3 and the password must be filled with 0xff bytes for this
PHY communication to work.
This extends the mdio-i2c driver to support this protocol by adding a
special parameter to mdio_i2c_alloc function via which this RollBall
protocol can be selected.

There are a few Ocelot chips that contain the logic for this bus, but are
controlled externally. Specifically the VSC7511, 7512, 7513, and 7514. In
the externally controlled configurations these registers are not
memory-mapped.
Add support for these non-memory-mapped configurations.

This reverts commit f8217275b57aa48d98cc42051c2aac34152718d6.
There are a few more issues to fix that have been reported in the thread
for the original series [1]. We'll need to fix those before this will work.
So, revert it for now.

Now that fw_devlink=on by default and fw_devlink supports interrupt
properties, the execution will never get to the point where
driver_deferred_probe_check_state() is called before the supplier has
probed successfully or before deferred probe timeout has expired.
So, delete the call and replace it with -ENODEV.

Error values inside the probe function must be < 0. The ENOMEM return
value has the wrong sign: it is positive instead of negative.

Add reset assertion/deassertion for Aspeed MDIO. There are 4 MDIO
controllers embedded in Aspeed AST2600 SOC and share one reset control
register SCU50[3]. To work with old DT blobs which don't have the reset
property, devm_reset_control_get_optional_shared is used in this change.
