f51a2f8496 net: smc911x: Pull MII registration into separate function
Pull the MII interface registration into separate function to avoid the
ifdeffery in smc911x_initialize(). Moreover, adjust the fail path such
that we use goto labels.

9741795408 net: smc911x: Fix potential memleak() in init fail path
Fix memleak in the init fail path, where if allocation or registration
of MDIO bus fails, then ethernet interface is not unregistered and the
private data are not freed, yet the probe function reports a failure.

e7ab86d9b2 net: rtl8139: Fill in SPDX tag
The rtl8139 driver is derived from Etherboot driver, which is in
turn derived from Linux 8139too driver added in Linux 2.2.18pre14.
An undocumented change in Linux 2.4.10.2 added a new field to the
driver, MODULE_LICENSE("GPL"); . According to current Linux kernel
licensing rules, Documentation/process/license-rules.rst, quote:

	"GPL"	Module is licensed under GPL version 2. This
		does not express any distinction between
		GPL-2.0-only or GPL-2.0-or-later. The exact
		license information can only be determined
		via the license information in the
		corresponding source files.

And since the code does not contain any "future" clause, the tag
is therefore GPL-2.0 only.

a83ca0c280 net: dwc_eth_qos: Invalidate RX packet DMA buffer
This patch prevents an issue where the RX packet might have been
accessed by the CPU, which now has cached data from the packet in
the caches and possibly various write buffers, and these data may
be evicted from the caches into the DRAM while the buffer is also
written by the DMA.

By invalidating the buffer after the CPU accessed it and before the
DMA populates the buffer, it is assured that the buffer will not be
corrupted.

738ee270fe net: dwc_eth_qos: Invalidate RX descriptor before reading
The current code polls the RX desciptor ring for new packets by reading
the RX descriptor status. This works by accident, as the RX descriptors
are often in non-cacheable memory. However, the driver does support use
of RX descriptors in cacheable memory.

This patch adds a missing RX descriptor invalidation, which assures the
CPU will read a fresh copy of the RX descriptor instead of a cached one.

83858d8795 net: dwc_eth_qos: Correctly wrap around TX descriptor tail pointer
This code programs the next descriptor in the TX descriptor ring into
the hardware as the last valid TX descriptor. The problem is that if
the currenty descriptor is the last one in the array, the code will
not wrap around correctly and use TX descriptor 0 again, but instead
will use TX descriptor at address right past the TX descriptor ring,
which is the first descriptor in the RX ring.

Fix this by adding the necessary wrap-around.

4332d80617 net: dwc_eth_qos: Fully rewrite RX descriptor field 3
The RX descriptor field 3 should contain only OWN and BUF1V bits before
being used for receiving data by the DMA engine. However, right now, if
the descriptor was already used for receiving data and is being cleared,
the field 3 is only modified and the aforementioned two bits are ORRed
into the field. This could lead to a residual dirty bits being left in
the field 3 from previous transfer, and it generally does. Fully set the
field 3 instead to clear those residual dirty bits.

which were incorrect for FMan v3 devices (i.e. DTSEC,
TGEC) and had weird formatting (i.e. FM1@DTSEC6, FM1@TGEC1).
The legacy code is left unchanged in this respect.

Add cache flush to zynq_gem_free_pkt. This is necessary

The cache_invalidate in the zynq_gem_recv function would cause
the modifications to the buffer to overwrite the DMA from the GEM,
if cache coherency is not enabled in the GEM, the next time the

Flushing the cache when the buffer is no longer in use by the

4fb2264b28 armv8/ls1046ardb: RGMII ports require internal delay
The correct setting for the RGMII ports on LS1046ARDB 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.

1c1f4f0a4b net: phy: marvell: Unify 88E151x series phy_driver
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.

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.

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.

bcee8d6764 dm: gpio: Allow control of GPIO uclass in SPL
At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.

Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.

Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.

This allows us to remove the hacks in config_uncmd_spl.h and
Makefile.uncmd_spl (eventually those files should be removed).

Ken Ma <make@marvell.com> in Marvell's own downstream repo:
https://github.com/MarvellEmbeddedProcessors/u-boot-marvell/commit/c81dc39.

The above refrenced work was based on an MVMDIO implementation that
never made it into U-Boot.  With this patch the mvpp2 driver switches
to use the new MVMDIO driver that is based on a more universal
mdio-uclass implementation.

623948377a net: mvpp2: mark phy as invalid in case of missing appropriate driver
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.

This patch fixes the issue with the link always down on MCBIN board.

nhed: added NULL deref test.

13b725fd24 net: mvpp2x: fix traffic stuck after PHY start error
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.

Based on commit 27708eb5481b ("net: phy: dp83867: IO impedance is not

The driver would only set the IO impedance value when RGMII internal delays
were enabled.  There is no reason for this.  Move the IO impedance block
out of the RGMII delay block.

20f7ea4c35 net: phy: dp83867: rework delay rgmii delay handling
Based on commit c11669a2757e ("net: phy: dp83867: Rework delay rgmii delay
handling") of mainline linux kernel.

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.

b3b9b128d5 net: phy: dp83867: Add ability to disable output clock
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.

2a7232371a NET: DW: fix regression for ARC boards
The commit
642b80d256 ("net: designware: drop compatible altr, socfpga-stmmac")
breaks designware ethernet for all ARC boards. It removes
"altr, socfpga-stmmac" compatible from "drivers/net/designware.c"
without changing compatible in the boards which use it.

Fix that by adding "snps,arc-dwmac-3.70a" compatible string to
"drivers/net/designware.c" and using it in ARC boards device tree.

5ccd657b6d net: macb: Fix rx buffer cache handling
With commit c6d07bf440 ("net/macb: increase RX buffer size for GEM")
ethernet support does not work any more with d-cache enabled on the
AT91SAM. The reason is, that MACB_RX_BUFFER_SIZE was changed from 4096
to 128 but this change was not refected in the rx_buffer flush and
invalidate functions, as these also use this macro.

This patch now fixes this by calculating the rx buffer size correctly
again in those functions. With this change, ethernet works again
reliably on my AT91SAM board.

8bd37ce3cd drivers: net: add marvell MDIO driver
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.

This driver supports SMI IEEE for 802.3 Clause 22 and XSMI for IEEE
802.3 Clause 45.

This patch also adds device tree binding for marvell MDIO driver.

1c8ad08674 net: tsec: Change compatible strings to match Linux
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.

4ee587e2cf net: designware: remove mdio bus on probe failure
The designware eth driver registers an mdio bus during probe, but if no
PHY is found, this bus is never removed although probe failes and the
driver is shown as not probed in the dm tree.

This later leads to errors when e.g. the mii or mdio commands try to
use available mdio buses because the mdio bus is still registered but
all corresponding data structures are invalid because probe failed.

Fix this by unregistering the mdio bus on probe failure (just as it is
unregistered in the .remove callback, too).

c2df9b49ce net: phy: ti: Use default values for tx/rx delay and fifo size
When not using DM_ETH, these PHY settings are programmed with default
values hardcoded into the driver.  When using DM_ETH, they should come
from the device tree.  However, if the device tree does not have the
properties, the driver will silent use -1.  Which is entirely out of
range, programs nonsense into the PHY's registers, and does not work.

Change this to use the same defaults as non-DM_ETH if the device tree is
lacking the properties.

As an alternative, the kernel driver for the phy will display an error
message and fail if the device tree is lacking.

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'.

6314d1c8c0 net: phy: micrel: Find Micrel PHY node correctly
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
unaffected by this change.

The changes were tested on a sama5d3xcm.

83f71ef558 net: phy: micrel: Use correct skew values on KSZ9021
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).
