We have encountered circumstances when a board design does not include
pull-up resistors on the external MDIO buses which are not used. This
leads to the MDIO data line not being pulled-up, thus the MDIO controller
will always see the line as busy.
Without a timeout in the MDIO bus driver, the execution is stuck in an
infinite loop when any access is initiated on that external bus.
Add a timeout in the driver so that we are protected in this
circumstance. This is similar to what is being done in the Linux
xgmac_mdio driver.

The pinmux choice for the RMII/RGMII pins the EMAC is connected to is
not dependent on the EMAC IP, but on the SoC it is integrated in.
Deriving the pinmux from the DT compatible string (as we do at the
moment) will thus cause problems with certain EMAC IP / SoC combinations.
To avoid this exact issue with the H616, let's use our Kconfig MACH
symbols to choose the correct pinmux setup.

At the moment we only consider the EPHY register for those SoCs were
we actually have an internal PHY to configure. However even other SoCs
have this register, an expect the EPHY select bit to be cleared for
proper operation with an external PHY.
Rework sun8i_emac_set_syscon_ephy() to be called regardless of the EMAC
model, and clear the H3_EPHY_SELECT bit if no internal PHY is used.
We get away without it so far because SoCs like the A64 clear this bit
on reset, but we need to explicitly clear it on the H616, for instance.
The Linux driver does so as well.

The phydev structure has a PHY OF node pointer in it, use that OF node
first when looking up PHY OF node properties, since that is likely the
correct PHY OF node pointer. If the pointer is not valid, which is the
case e.g. on legacy DTs, fall back to parsing MAC ethernet-phy subnode.

is virt_to_phys() so switch to using this macro.

So far all GBit users of the sun8i-emac driver were using the "rgmii"
PHY mode, even though this turns out to be wrong. It just worked because
the PHY driver doesn't do the proper setup (yet).
In fact for most boards the "rgmii-id" or "rgmii-txid" PHY modes are the
correct ones.
To allow the DTs to describe the phy-mode correctly, and to stay
compatible with Linux, at least allow those other RGMII modes in the
driver.
This avoids breakage if mainline DTs will be synced with U-Boot.

Second set of u-boot-atmel features for 2021.04 cycle
This feature set includes macb updates for all interfaces and new
sama7g5 variant support; micrel ksz9031 DLL support; a new board from
Giant based on Adafruit feather form factor which contains a SAMA5D27
SoC; several fixes regarding the NAND flash PMECC block; and pincontrol
drive strength support for pio4 controller.
This patch adds ethernet driver for MediaTek MT7620 SoC.
The MT7620 SoC has a built-in ethernet (Frame Engine) and a built-in
7-port switch and two xMII interfaces (can be MII/RMII/RGMII).
The port 0-3 of the switch connects to intergrited FE PHYs. Port 4 can be
configured to connect to either the intergrited FE PHY, or the xMII.
Port 5 always connects to the xMII. Port 6 is the CPU port.
This driver supports MT7530 giga switch connects to port 5.

any additional "bad packet" messages if there are no more packets in
