63d3192984 net: phy: dp83867: add workaround for incorrect RX_CTRL pin strap
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)).

It further advises that if a board has this pin strapped in mode 1 and
mode 2, then bit[7] of Configuration Register 4 (address 0x0031) must
be cleared to 0. This is to ensure proper operation of PHY.

Since it is not possible to detect in software if RX_DV/RX_CTRL pin is
incorrectly strapped, add a device-tree property to advertise this and
allow corrective action in software.

Add support for Cortina CS4223 10G PHY
  - As per the CS4223 specs, an EEPROM module is
    connected to the PHY. At startup the PHY reads
    the firmware line and tries to load the firmware
    into the internal memory.
  - This driver reads the EEPROM status

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

b321c44ac9 net/phy/cortina: Add No firmware upload option
Current Cortina phy driver assumes that firmware upload
is required during initialization and is dependent
on presence of corresponding macros like CONFIG_CORTINA_FW_ADDR

But Cortina phy has provision to store phy firmware in

EEPROM does not require firmware upload.

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.

both bits set.

Hence, this patch changes the behavior in the PHY_INTERFACE_MODE_RGMII

30cbb524bc net: phy: meson-gxl: detect LPA corruption
This patch is ported from the Linux patch posted at [1] and applied to
net tree as commit f1e2400a80ff.

The purpose of this change is to fix the incorrect detection of the link
partner (LP) advertised capabilities which sometimes happens with this PHY
(roughly 1 time in a dozen)

This issue may cause the link to be negotiated at 10Mbps/Full or
10Mbps/Half when 100MBps/Full is actually possible. In some case, the link
is even completely broken and no communication is possible.

To detect the corruption, we must look for a magic undocumented bit in the
WOL bank (hint given by the SoC vendor kernel) but this is not enough to
cover all cases. We also have to look at the LPA ack. If the LP supports
Aneg but did not ack our base code when aneg is completed, we assume
something went wrong.

The detection of a corrupted LPA triggers a restart of the aneg process.
This solves the problem but may take up to 6 retries to complete.

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.

cebf3f558e net: phy: realtek: Only force master mode on rtl8211b/c
Commit 525d187af ("net: phy: Optionally force master mode for RTL PHY")
added the define to force the PHY into master mode. Unfortunatly this is
an all or nothing switch. So it applies to either all PHY's or no PHY's.

The bug that define tried to solve was a buggy PLL in the RTL8211C only.

The Olimex OLinuXino Lime2 has gotten an upgrade where the PHY was
replaced with an RTL8211E. With this define however, both lime2 boards
are either forced to master mode or not. We could of course have a
binary for each board, but the following patch fixes this by adding a
'quirk' to the flags to the rtl8211b and rtl8211c only. It is now
possible to force master mode, but only have it apply to the rtl8211b
and rtl8211c.

563d8d9358 net: phy: Realtek RTL8211B/C PHY ID fix
The RTL8211B_driver structure in drivers/net/phy/realtek.c contains a
wrong PHY ID (0x1cc910 instead of 0x1cc912) in the uid field.

The lowest four bits of the PHY ID encode the chip revision (B+C/D/E/F)
of the RTL8211 and the code originally applied a mask of 0xfffff0 to
the PHY ID, so that matching the PHY ID to the appropriate driver code
was only done on the chip type (RTL8211), but not on a specific
revision.

After introduction of support for the RTL8211E, which needed another
startup function than the older chip revisions, commit
4220504767 changed the mask to 0xffffff
to make the chip revision relevant for the match, but didn't provide
the now-relevant lower bits of the uid field for the RTL8211B/C.

Fix this by setting the full PHY ID in the RTL8211B_driver uid field.

525d187afb net: phy: Optionally force master mode for RTL PHY
This patch introduces CONFIG_RTL8211X_PHY_FORCE_MASTER. If this
define is set, RTL8211x PHYs (except for the RTL8211F) will have their
1000BASE-T master/slave autonegotiation disabled and forced to master
mode.

This is helpful for PHYs like the RTL8211C which produce unstable links
in slave mode. Such problems have been found on the A20-Olimex-SOM-EVB
and A20-OLinuXino-Lime2.

There is no proper way to identify affected PHYs in software as the
RTL8211C shares its UID with the RTL8211B. Thus, this fix requires
the introduction of an #ifdef.

903d384d40 net: phy: atheros: Fix problem with phy_reset() clearing BMCR
In commit <a058052c358c> [net: phy: do not read configuration register on
reset], phy_reset() will clear the BMCR register. Bit 12(AUTO_NEGOTIATION)
is cleared too. It causes auto-negotiation timeout error on Atheros's
PHY AR8033.

To fix this problem, genphy_config_aneg() and genphy_restart_aneg()
needs to be called in ar8035_config() to enable and restart
auto-negotiation.

6a10bc5be8 net: phy: realtek: Use generic genphy_parse_link() for RTL8211E
The problem with current implementation is that SPDDONE bit is 1
but link bit is zero. That's why phydev->link is setup to 0
which ending up in driver failure that link is not up.

Log:
Zynq> dhcp
ethernet@e000b000 Waiting for PHY auto negotiation to complete.......
done
ethernet@e000b000: No link.

There is at least 1ms delay between spddone bit and link up.

Use genphy_read_status() instead of realtek implemenation which is
working with page 11. Linux driver is also using generic implementation.

a8c3eca433 net: phy: marvell: Fix problem with phy_reset() clearing BMCR
With commit a058052c [net: phy: do not read configuration register on
reset], phy_reset() will clear the BMCR register. Resulting in bit 12
being cleared (A/N enable). This leads to autonegotiation link problems,
at least on the Marvell Armada ClearFog board. I suspect that other
boards using this driver will be affected as well.

At the of m88e1111s_config(), phy_reset() is called. This is not needed
for the PHY to load the changed configuration, as phy_reset() is called
a few lines before already. So lets call genphy_restart_aneg() here
instead to start the AN correctly.

Tested on clearfog.
