Marc reported that he was not getting the PHY library adjust_link()
callback function to run when calling phy_stop() + phy_disconnect()
which does not indeed happen because we set the state machine to
PHY_HALTED but we don't get to run it to process this state past that
point.
Fix this with a synchronous call to phy_state_machine() in order to have
the state machine actually act on PHY_HALTED, set the PHY device's link
down, turn the network device's carrier off and finally call the
adjust_link() function.

In preparation for having the bcmgenet driver migrate over the

passing integrating specific details like bus name, wait function to

UNIMAC_MDIO_DRV_NAME and moving it to the platform_data header.

In preparation for having multiple GENET instances in a system (up to
3), make sure that we do include the bus instance number in the name of
the MDIO bus such that we change it from "unimac-mdio" to
"unimac-mdio-0" for instance.
So far, the only user of this driver is using Device Tree, which uses a
lookup/parenting based technique to map PHY devices to their respective
MDIO bus controllers, hence causing no additional changes.

I still see build errors in randconfig builds and have had this
patch for a while to locally work around it:
drivers/built-in.o: In function `xgene_mdio_probe':
mux-core.c:(.text+0x352154): undefined reference to `of_mdiobus_register'
mux-core.c:(.text+0x352168): undefined reference to `mdiobus_free'
mux-core.c:(.text+0x3521c0): undefined reference to `mdiobus_alloc_size'
The idea is that CONFIG_MDIO_BUS now reflects whether the mdio_bus
code is built-in or a module, and other drivers that use the core
code can simply depend on that, instead of having a complex
dependency line.

mdio_mux_init parses the child nodes of the MDIO mux. When using
"mdio-mux-mmioreg" the child nodes are describing the register value
that is written to switch between the MDIO busses.
The change which makes the error messages more verbose changed the
parsing of the "reg" property from a simple of_property_read_u32 call
to of_mdio_parse_addr. On a Khadas VIM (based on the Meson GXL SoC,
which uses mdio-mux-mmioreg) this prevents registering the MDIO mux
(because the "reg" values on the MDIO mux child nodes are 0x2009087f
and 0xe40908ff) and leads to the following errors:
mdio-mux-mmioreg c883455c.eth-phy-mux: /soc/periphs@c8834000/eth-phy-mux/mdio@e40908ff PHY address -469169921 is too large

mdio-mux-mmioreg c883455c.eth-phy-mux: failed to register mdio-mux bus /soc/periphs@c8834000/eth-phy-mux
(as a result of that ethernet is not working, because the PHY which is
connected through the mux' child MDIO bus, which is not being
registered).
Fix this by reverting the change from of_mdio_parse_addr to
of_mdio_parse_addr.

The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
supported (see note below Table 5 (4-Level Strap Pins)).
There are some boards which have the pin strapped this way and need
software workaround suggested by the data manual. Bit[7] of
Configuration Register 4 (address 0x0031) must be cleared to 0. This
ensures proper operation of the PHY.
Implement driver support for device-tree property meant to advertise
the wrong strapping.

The function, skb_complete_tx_timestamp(), used to allow passing in a

call sites, all of which are in the dp83640 driver, were fixed up.
Even though the kernel-doc was subsequently updated in commit
7a76a021cd5a292be875fbc616daf03eab1e6996 ("net-timestamp: Update
skb_complete_tx_timestamp comment"), still a bug fix from Manfred
Rudigier came into the driver using the old semantics. Probably
Manfred derived that patch from an older kernel version.
This fix should be applied to the stable trees as well.

The commit ("net/phy: micrel: Add workaround for bad autoneg") fixes an
autoneg failure case by resetting the hardware. This turns off
intterupts. Things will work themselves out if the phy polls, as it will
figure out it's state during a poll. However if the phy uses only
intterupts, the phy will stall, since interrupts are off. This patch
fixes the issue by calling config_intr after resetting the phy.

Add phylib support for the Marvell Alaska X 10 Gigabit PHY (MV88X3310).
This phy is able to operate at 10G, 1G, 100M and 10M speeds, and only
supports Clause 45 accesses.
The PHY appears (based on the vendor IDs) to be two different vendors
IP, with each devad containing several instances.
This PHY driver has only been tested with the RJ45 copper port, fiber
port and a Marvell Armada 8040-based ethernet interface.
It should be noted that to use the full range of speeds, MAC drivers
need to also reconfigure the link mode as per phydev->interface, since
the PHY automatically changes its interface mode depending on the
negotiated speed.

Most of the PHYs supported by the SMSC driver have a counter of symbol
errors. This is 16 bit wide and wraps around when it reaches its
maximum value.

functions m88e1510_get_temp_critical, m88e1510_set_temp_critical and
m88e1510_get_temp_alarm can be made static as they not need to be
in global scope.
Cleans up sparse warnings:
"symbol 'm88e1510_get_temp_alarm' was not declared. Should it be static?"
"symbol 'm88e1510_get_temp_critical' was not declared. Should it be
static?"

If any errors are encountered while walking the device tree structure of
the MDIO bus for children, the code may silently continue, silently
exit, or throw an error and exit. This make it difficult for device
tree writers to know there is an error. Also, it makes any error in a
child entry of the MDIO bus be fatal for all entries. Instead, we
should provide verbose errors describing the error and then attempt to
continue if it all possible. Also, use of_mdio_parse_addr()

use of_mdio_parse_addr() in place of an OF read of reg and a bounds
check (which is litterally the exact same thing that
of_mdio_parse_addr() does)
