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

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.

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 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.

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.
