a744a284e3 net: phy: Add support for ethernet-phy-id with gpio reset
Ethernet phy like dp83867 is using strapping resistors to setup PHY
address. On Xilinx boards strapping is setup on wires which are connected
to SOC where internal pull ups/downs influnce phy address. That's why there
is a need to setup pins properly (via pinctrl driver for example) and then
perform phy reset. I can be workarounded by reset gpio done for mdio bus
but this is not working properly when multiply phys sitting on the same
bus. That's why it needs to be done via ethernet-phy-id driver where dt
binding has gpio reset per phy.

DT binding is available here:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ethernet-phy.yaml

The driver is are reading the vendor and device id from valid phy node
using ofnode_read_eth_phy_id() and creating a phy device.
Kconfig PHY_ETHERNET_ID symbol is used because not every platform has gpio
support.

f11513d997 net: phy: realtek: Add tx/rx delay config for 8211e
Some boards need to change the tx/rx delay config in order for
gigabit Ethernet to work.

In Linux commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx
delay config"), Realtek documented the bits for overriding the delays
from the hardware straps.

Copy the logic from linux, so the delay config is set from the PHY's
interface type (the phy-mode property in the device tree).

This removes the need for a one-off workaround for the Pine A64+ board.

bc0e578f90 net: phy: Add support for TI PHY init
ti_phy_init function was allocated to the DP83867 PHY.  This function
name is to generic for a specific PHY.  The function can be moved to a
TI specific file that can register all TI PHYs that are defined in the
defconfig.  The ti_phy_init file will contain all TI PHYs initialization
so that only phy_ti_init can be called from the framework.

In addition to the above the config flag for the DP83867 needs to be changed
in the Kconfig and dependent defconfig files. The config flag that was
used for the DP83867 was also generic in nature so a more specific
config flag for the DP83867 was created.

f641a8ac93 phy: Add support for the NC-SI protocol
This introduces support for the NC-SI protocol, modelled as a phy driver
for other ethernet drivers to consume.

NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).

This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).

The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
field definitions.

77b508d34b net: phy: micrel: Allow KSZ8xxx and KSZ90x1 to be used together
Commit d397f7c45b ("net: phy: micrel: Separate KSZ9000 drivers from
KSZ8000 drivers") separated the KSZ8xxx and KSZ90x1 drivers and warns
that you shouldn't select both of them due to a device ID clash between
the KSZ9021 and the KS8721, asserting that "it is highly unlikely for a
system to contain both a KSZ8000 and a KSZ9000 PHY". Unfortunately
boards like the SAMA5D3xEK do contain both types of PHY, but fortunately
the Linux Micrel PHY driver provides a solution by using different PHY
ID and mask values to distinguish these chips.

This commit contains the following changes:

- The PHY ID and mask values for the KSZ9021 and the KS8721 now match
those used by the Linux driver.
- The warnings about not enabling both drivers have been removed.
- The description for PHY_MICREL_KSZ8XXX has been corrected (these are
10/100 PHYs, not GbE PHYs).
- PHY_MICREL_KSZ9021 and PHY_MICREL_KSZ9031 no longer select PHY_GIGE
since this is selected by PHY_MICREL_KSZ90X1.
- All of the relevant defconfig files have been updated now that
PHY_MICREL_KSZ8XXX does not default to 'Y'.

d47cfdbd31 net: phy: realtek: Introduce quirk to mark RXC not stoppable
When EEE is supported by the PHY and the driver allows it, libphy in the
kernel is configuring the PHY to stop receiving the xMII clock while it
is signaling LPI. While this (usually) works fine in the kernel this is
causing issues in U-Boot when rebooting from the linux kernel with this
bit set (without having the possibility to reset the PHY) where the PHY
suddenly stops working.

A new quirk is introduced to unconditionally reset this bit. If the
quirk is not enabled using the proper configuration symbol, the PHY state
is not changed.

b30c419040 Move CONFIG_PHY_ADDR to Kconfig
CONFIG_PHY_ADDR is used for old-style configuration. This makes
impossible changing the PHY address, if multiple boards share a same
config header file (for example include/configs/sunxi-common.h).

Moving this to Kconfig helps overcoming this issue. It's defined
as entry inside PHYLIB section.

After the implemention, moveconfig was run. The issues are:
	- edb9315a	- CONFIG_PHYLIB is not enabled. Entry is
			  deleted.

	- ds414		- CONFIG_PHYLIB is in incompatible format:
			  { 0x1, 0x0 }. This entry is also deleted.

	- devkit3250	- The PHY_ADDR is in hex format (0x1F).
			  Manually CONFIG_PHY_ADDR=31 is added in
			  the defconfig.

After the changes the suspicious defconfigs passes building.

d397f7c45b net: phy: micrel: Separate KSZ9000 drivers from KSZ8000 drivers
The KS8721BL and KSZ9021 PHYs are software-incompatible, yet they
share the same ID. Drivers for bothe PHYs cannot safely coexist, so
the solution was to use #ifdefs to select between the two drivers.

As a result KSZ9031, which has a unique ID, is now caught in the
crossfire. Unless CONFIG_PHY_MICREL_KSZ9031 is defined, the KSZ9031
will not function properly, as some essential configuration code is
ifdef'd-out.

To prevent such situations, move the KSZ9000 drivers to a separate
file, and place them under a separate Kconfig option. While it is
possible to enable both KSZ8000 and KSZ9000 drivers at the same time,
the assumption is that it is highly unlikely for a system to contain
both a KSZ8000 and a KSZ9000 PHY, and that only one of the drivers
will be enabled at any given time.

db40c1aa1c drivers/net/phy: add fixed-phy / fixed-link support
This patch adds support for having a "fixed-link" to some other MAC
(like some embedded switch-device).

For this purpose we introduce a new phy-driver, called "Fixed PHY".

Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
described with a subnode below ethernet interface.

Most ethernet drivers (unfortunately not all are following same scheme
for searching/attaching phys) are calling "phy_connect(...)" for getting
a phy-device.
At this point we link in, we search here for a subnode called "fixed-
link", once found we start phy_device_create(...) with the special phy-
id PHY_FIXED_ID (0xa5a55a5a).

During init the "Fixed PHY" driver has registered with this id and now
gets probed, during probe we get all the details about fixed-link out of
dts, later on the phy reports this values.
