The correct setting for the RGMII ports on LS1043ARDB is to
enable delay on both Rx and Tx so the interface mode used must
be PHY_INTERFACE_MODE_RGMII_ID. There is a pull-up that turns
on Rx internal delay by default and the u-boot does not
override that (yet) so in u-boot the interface is functional.
In Linux the PHY driver is clearing the Rx delay for the
"rgmii-txid" mode and the reception does not work.
Changing the RGMII mode to internal delay here ensures that
device tree fix-ups for the PHY connection type turn on both
Tx and Rx internal delay in Linux.

The PHY models of the Marvell 88E151x series are not reliably
distinguishable by their uid / PHY identifiers.
The 88E1510, 88E1512, 88E1514 and 88E1518 all have the same OUI and
model number and bits 3:0 in the PHY Identifier 2 (Page 0, Reg 3) are
described as HW revision number, but both 88E1510 and 88E1518 PHYs were
observed with the same HW rev number (1).
Before commit 83cfbeb0df ("net: phy: Fix mask so that we can identify
Marvell 88E1518"), the 88E151x were detected because the HW revision
bits were masked from the uid. After that change, 88E1510/12/18 were all
detected as 88E1518 and the 88E1510 specific code was no longer run.
I modified the mask to again ignore all four HW revision bits, removed
the 88E1510 specific code (board-specific LED/INTn setup), which was not
called since late 2016 anyway and renamed the config function and
phy_driver struct to the better fitting 88e151x.
The uid and mask bits 3:0 are now again the same as in the Linux kernel.

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.

The implementation of dma_map_single() and dma_unmap_single() is
exactly the same for all the architectures that support them.
Factor them out to <linux/dma-mapping.h>, and make all drivers to
include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>.
If we need to differentiate them for some architectures, we can
move the generic definitions to <asm-generic/dma-mapping.h>.
Add some comments to the helpers. The concept is quite similar to
the DMA-API of Linux kernel. Drivers are agnostic about what is
going on behind the scene. Just call dma_map_single() before the
DMA, and dma_unmap_single() after it.

(KSZ8081MNX/RNB) pin. If a pull-down is missing, or if the pin has a

I've noticed that in most cases when genphy_update_link() is called, the
ethernet driver (mt7628-eth in this case) fails with the first ethernet
packets. Resulting in a timeout of the first tftp command. Increasing
the delay in the link check look from 1 to 50 ms and moving it below the
BMSR register read fixes this issue, resulting in a stable ethernet
traffic, even after initial link autonogotiation.

If the phy doesn't match with any existing u-boot drivers, the phy
framework will connect it to the generic one which uid ==
0xffffffff. In this case, act as if the phy wouldn't be declared in
dts. Otherwise, in case of 3310 (for which the driver doesn't exist)
the link is marked as always down. Removing phy entry from dts in case
of 3310 is not a good option because it is required for the
phy_fw_down procedure.

Issue:
- Network stuck if autonegotion fails.
Issue root cause:
- When autonegotiation fails during port open procedure, the packet
processor configuration does not finish and open procedure exits
with error.
- However, this doesn't prevent u-boot network framework from
calling send and receive procedures.
- Using transmit and receive functions of misconfigured packet
processor will cause traffic to get stuck.
Fix:
- Continue packet processor configuration even if autonegotiation
fails. Only error message is triggered in this case.
- Exit transmit and receive functions if there is no PHY link
indication.
- U-boot network framework now calls open procedure again during next
transmit initiation.

The current code is assuming the reset default of the delay control
register was to have delay disabled. This is what the datasheet shows as
the register's initial value. However, that's not actually true: the
default is controlled by the PHY's pin strapping.
This patch:
- insures the other direction's delay is disabled If the interface mode is
selected as RX or TX delay only
- validates the delay values and fail if they are not in range
- checks if the board is strapped to have a delay and is configured to use
"rgmii" mode and warning is generated that "rgmii-id" should have been
used.

Based on commit 13c83cf8af0d ("net: phy: dp83867: Add ability to disable
output clock") of mainline linux kernel.
Generally, the output clock pin is only used for testing and only serves as
a source of RF noise after this. It could be used to daisy-chain PHYs, but
this is uncommon. Since the PHY can disable the output, make doing so an
option. I do this by adding another enumeration to the allowed values of
ti,clk-output-sel.
The code was not using the value DP83867_CLK_O_SEL_REF_CLK as one might
expect: to select the REF_CLK as the output. Rather it meant "keep clock
output setting as is", which, depending on PHY strapping, might not be
outputting REF_CLK.
Change this so DP83867_CLK_O_SEL_REF_CLK means enable REF_CLK output.
Omitting the property will leave the setting as is (which was the previous
behavior in this case).
Out of range values were silently converted into DP83867_CLK_O_SEL_REF_CLK.
Change this so they generate an error.

This patch adds a separate driver for the MDIO interface of the
Marvell Ethernet controllers based on driver model. There are two
reasons to have a separate driver rather than including it inside
the MAC driver itself:
*) The MDIO interface is shared by all Ethernet ports, so a driver
must guarantee non-concurrent accesses to this MDIO interface. The
most logical way is to have a separate driver that handles this
single MDIO interface, used by all Ethernet ports.
*) The MDIO interface is the same between the existing mv643xx_eth
driver and the new mvneta/mvpp2 driver. Even though it is for now
only used by the mvneta/mvpp2 driver, it will in the future be
used by the mv643xx_eth driver as well.

In the case of the tsec network driver, so far there has been no
mainline user of DM_ETH where the DT bindings get used.
In the case of the mdio bus, it looks like the "fsl,tsec-mdio" string
was made up for the documentation, but there is no mainline code that
parses the "compatible" property anyway.
In both cases, there are no DT blobs that contain the old strings.
So change the documentation to "fsl,etsec2" for the Ethernet ports and
"fsl,etsec2-mdio" for the MDIO buses, which are strings that Linux also
uses, at least for LS1021A. More compatible strings can be added once
other (PowerPC) SoCs are migrated to DM_ETH.
The current ls1021a.dtsi doesn't match what was documented for the MDIO
buses anyway (the "compatible" is "gianfar" currently). This will be
fixed in the next patch.

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'.

In some of the device trees that specify skew values for KSZ90x1 PHYs
the values are stored (incorrectly) in the MAC node, whereas in others
it is in an 'ethernet-phy' subnode. Previously the code would fail to
find and program these skew values, so this commit changes it to look
for an "ethernet-phy" subnode first, and revert to looking in the MAC
node if there isn't one.
The device trees affected (where the skew values are in a subnode) are
imx6qdl-icore-rqs.dtsi, r8a77970-eagle.dts, r8a77990-ebisu.dts,
r8a77995-draak.dts, salvator-common.dtsi, sama5d3xcm.dtsi,
sama5d3xcm_cmp.dtsi, socfpga_cyclone5_vining_fpga.dts,
socfpga_stratix10_socdk.dts and ulcb.dtsi. Before this change the skew
values in these device trees would be ignored.
The device trees where the skew values are in the MAC node are
socfpga_arria10_socdk.dtsi, socfpga_arria5_socdk.dts,
socfpga_cyclone5_de0_nano_soc.dts, socfpga_cyclone5_de10_nano.dts,
socfpga_cyclone5_de1_soc.dts, socfpga_cyclone5_is1.dts,
socfpga_cyclone5_socdk.dts, socfpga_cyclone5_sockit.dts. These should be

Commit ff7bd212cb ("net: phy: micrel: fix divisor value for KSZ9031
phy skew") fixed the skew value divisor for the KSZ9031, but left the
code using the same divisor for the KSZ9021, which is incorrect.
The preceding commit c16e69f702 ("net: phy: micrel: add documentation
for Micrel KSZ90x1 binding") added the DTS documentation for the
KSZ90x1, changing it from the equivalent file in the Linux kernel to
correctly state that for this part the skew value is set in 120ps steps,
whereas the Linux documentation and driver continue to this day to use
the incorrect value of 200 that came from the original KSZ9021 datasheet
before it was corrected in revision 1.2 (Feb 2014).
This commit sorts out the resulting confusion in a consistent way by
making the following changes:
- Update the documentation to be clear about what the skew values mean,
in the same was as for the KSZ9031.
- Update the Micrel PHY driver to select the appropriate divisor for
both parts.
- Adjust all the device trees that state skew values for KSZ9021 PHYs to
use values based on 120ps steps instead of 200ps steps. This will result
in the same values being programmed into the skew registers as the
equivalent device trees in the Linux kernel do, where it incorrectly
uses 200ps steps (since that's where all these device trees were copied
from).

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.

The MMD PHY registers can be accessed by several means:
1. Using two new MMD access function hooks in the PHY driver. These
functions can be implemented when the PHY driver does not support the
standard IEEE Compatible clause 45 access mechanism described in clause
22 or if the PHY uses its own non-standard access mechanism.
2. Direct access for C45 PHYs and C22 PHYs when accessing the reachable
DEVADs.

Since the introduction of the driver, some memory in IRAM is reserved for
the TX buffers.
However there are not used but instead of it, it is the buffer provided
by the net stack which is used. As stated in the comment of the driver,
not using the IRAM buffer could cause cache issue and lower the
throughput.
For the second argument it is less the case for transmitting buffers
because the throughput gain in IRAM is mitigated by the time to copy the
data from RAM to IRAM, but the first argument is still valid and indeed

doing it over and over again is start() function. This requires us to
keep the clock enabled while the driver is in use. This significantly
reduces the time between transfers as the PHY doesn't have to restart
autonegotiation between transfers, which takes forever.

I've noticed that the first ethernet packet after PHY link establishment
is not tranferred correctly most of the time on my AT91SAM9G25 board.
Here I usually see a timeout of a few seconds, which is quite
annoying.
Adding a small delay (10ms in this case) after the link establishment
helps to solve this problem. With this patch applied, this timeout
on the first packet is not seen any more.

some dpmacs in armv8a based freescale layerscape SOCs can be
configured via both serdes(sgmii, xfi, xlaui etc) bits and via
EC*_PMUX(rgmii) bits in RCW.
e.g. dpmac 17 and 18 in LX2160A can be configured as SGMII from
serdes bits and as RGMII via EC1_PMUX/EC2_PMUX bits
Now if a dpmac is enabled by serdes bits then it takes precedence
over EC*_PMUX bits. i.e. in LX2160A if we select serdes protocol
that configures dpmac17 as SGMII and set the EC1_PMUX as RGMII,
then the dpmac is SGMII and not RGMII.
Therefore, in fsl_rgmii_init function of SOC, we will check if the
dpmac is enabled or not? if it is (fsl_serdes_init has already enabled
the dpmac), then don't enable it.

This driver was written for Arria10, but it applies to Gen5, too.
The main difference is that Gen5 has 2 MACs (Arria10 has 3) and the
syscon bits are encoded in the same register, thus an offset is needed.
This offset is already read from the devicetree, but for Arria10 it is
always 0, which is probably why it has been ignored. By using this
offset when writing the phy mode into the syscon regiter, we can use
this driver to set the phy mode for both of the MACs on Gen5.
Since the PHY mode bits in sysmgr are the same even for Stratix10,
let's drop the detection of the sub-mach by checking compatible
version and just use the same code for all FPGAs.
To work correctly, this driver depends on SYSCON and REGMAP, so select
those via Kconfig when it is enabeld.
Tested on socfpga_socrates (where the 2nd MAC is connected, so a shift
offset is required).

For KSZ9021, all skew register fields are 4-bit wide.
For KSZ9031, the clock skew register fields are 5-bit wide.
The common code in ksz90x1_of_config_group calculating the combined
register value checks if the requested value is above the maximum
and uses this maximum if so. The calculation of this maximum uses
the register width, but the check itself does not. It uses a hardcoded
value of 0xf, which is too low in case of the 5-bit clock (0x1f).
This detail was probably lost during driver unification.
Effect (only for KSZ9031 clock skews): For values greater 900 (== 0ps),
this silently results in 1860 (== +960ps) instead of the requested one.

The VSC8574 PHY is a 4-port PHY that is 10/100/1000BASE-T, 100BASE-FX,
1000BASE-X and triple-speed copper SFP capable, can communicate with
the MAC via SGMII, QSGMII or 1000BASE-X, supports WOL, downshifting and
can set the blinking pattern of each of its 4 LEDs, supports SyncE as
well as HP Auto-MDIX detection.
This adds support for 10/100/1000BASE-T and SGMII/QSGMII link with the
MAC.
The VSC8574 has also an internal Intel 8051 microcontroller whose
firmware needs to be patched when the PHY is reset. If the 8051's
firmware has the expected CRC, its patching can be skipped. The
microcontroller can be accessed from any port of the PHY, though the CRC
function can only be done through the PHY that is the base PHY of the
package (internal address 0) due to a limitation of the firmware.
The GPIO register bank is a set of registers that are common to all PHYs
in the package. So any modification in any register of this bank affects
all PHYs of the package.

prepare for the upcoming support of VSC8574, use the phy_device.priv
pointer that will keep the function that holds code that is PHY-specific
and that should be called during config function.

The VSC8584 PHY is a 4-port PHY that is 10/100/1000BASE-T, 100BASE-FX,
1000BASE-X and triple-speed copper SFP capable, can communicate with the
MAC via SGMII, QSGMII or 1000BASE-X, supports downshifting and can set
the blinking pattern of each of its 4 LEDs, supports hardware offloading
of MACsec and supports SyncE as well as HP Auto-MDIX detection.
This adds support for 10/100/1000BASE-T and SGMII/QSGMII link with the
MAC.
The VSC8584 has also an internal Intel 8051 microcontroller whose
firmware needs to be patched when the PHY is reset. If the 8051's
firmware has the expected CRC, its patching can be skipped. The
microcontroller can be accessed from any port of the PHY, though the CRC
function can only be done through the PHY that is the base PHY of the
package (internal address 0) due to a limitation of the firmware.
The GPIO register bank is a set of registers that are common to all PHYs
in the package. So any modification in any register of this bank affects
all PHYs of the package.
The revA of the VSC8584 PHY (which is not and will not be publicly
released) should NOT patch the firmware of the microcontroller or it'll
make things worse, the easiest way is just to not support it.

The DP83867 when not properly bootstrapped - especially with LED_0 pin -
can enter N/A MODE4 for "port mirroring" feature.
To provide normal operation of the PHY, one needs not only to explicitly
disable the port mirroring feature, but as well stop some IC internal
testing (which disables RGMII communication).
To do that the STRAP_STS1 (0x006E) register must be read and RESERVED bit
11 examined. When it is set, the another RESERVED bit (11) at PHYCR
(0x0010) register must be clear to disable testing mode and enable RGMII
communication.

priv->phydev = phy_connect(priv->bus, priv->phyaddr, dev,
priv->interface);
<-- phydev is connected to dev which is UCLASS_ETH device
if (priv->phy_of_handle > 0)
dev_set_of_offset(priv->phydev->dev, priv->phy_of_handle);
<-- phydev->dev->node is overwritten by phy-handle DT node
- PHY driver in .config() callback
int node = dev_of_offset(dev);
<-- PHY driver uses overwritten dev->node
const void *fdt = gd->fdt_blob;
if (fdtdec_get_bool(fdt, node, "property"))
...
As result, UCLASS_ETH device can't be used any more for DT accessing.
This patch adds additional ofnode node field to struct phy_device which can
be set explicitly by network drivers and used by PHY drivers, so
overwriting can be avoided. Also add helper function phy_get_ofnode()
which will check and return phy_device->node or dev_ofnode(phydev->dev) for
backward compatibility with existing drivers.

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.

On the SPEAr600 SoC, which has the dwmac1000 variant of the IP block,
the DMA reset never succeeds when a MII PHY is used (no problem with a
GMII PHY). The designware_eth_init() function sets the
DMAMAC_SRST bit in the DMA_BUS_MODE register, and then
polls until this bit clears. When a MII PHY is used, with the current
driver, this bit never clears and the driver therefore doesn't work.
The reason is that the PS bit of the GMAC_CONTROL register should be
correctly configured for the DMA reset to work. When the PS bit is 0,
it tells the MAC we have a GMII PHY, when the PS bit is 1, it tells
the MAC we have a MII PHY.
Doing a DMA reset clears all registers, so the PS bit is cleared as
well. This makes the DMA reset work fine with a GMII PHY. However,
with MII PHY, the PS bit should be set.
We have identified this issue thanks to two SPEAr600 platform:
- One equipped with a GMII PHY, with which the existing driver was
working fine.
- One equipped with a MII PHY, where the current driver fails because
the DMA reset times out.

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.
