Since mt76x8an ver1 eco2, SDXC pins can be switched to the
following pinmap:
sd_d1 -> PAD_I2S_SDI
sd_d0 -> PAD_I2S_WS
sd_cmd -> PAD_I2S_CLK
sd_d3 -> PAD_I2C_SCLK
sd_d2 -> PAD_I2C_SD
sd_clk -> PAD_GPIO0
sd_wp -> PAD_TXD1
sd_cd -> PAD_RXD1
To use this pinmap, one would need to set ESD_MODE bit (bit 15)
to 1 in GPIO1_MODE and switch other used pads into GPIO mode.
In this mode, we don't need to switch ethernet pins to digital
pad.
Check ESD_MODE bit before applying AGPIO_CFG and use rt_sysc_m32
to set it.

The port initialisation is based on assumption that phy address and
port number is the same. SoC allow different numbers and some board
have it.
Use phy address instead the port number to make sure that correct
addresses are polled.
In situation when only one PHY with address 0x0 is conected to
port 4, autopolling is broken.
This patch make autopolling correct when port number and phy address
are different.

The phy handling code forces a phy mdio address and the switch port to
which a phy is attached to be the same. Albeit such a configuration is
used for most boards, it isn't for all.
Pass the switch port number to the ethernet phy connect functions, to
ensure the correct list entry is edited and not the list entry that
matches th phys mdio address.
Use the mdio address with mdiobus_get_phy instead of the port number,
to make sure the expected ethernet phy gets connected.

The whole logic in fe_phy_connect() is based on the asumption that mdio
address and switch port id are equal. Albeit it is true for most
boards, it doesn't is for all.
It isn't yet clear which subtargets/boards require the devicetree less
ethernet phy handling. Hence change the code in a way that it doesn't
touch ethernet phys which were early attached and are already handled.

Current code directly writes the FOE entry to hash_val+1 position
when hash collision occurs. However, it is found that this behavior
will cause the cache and the hardware FOE table to be inconsistent.
For example, there are three flows, and their hashed values are all
equal to 100. The first flow is written to the position of 100. The
second flow is written to the position of 100+1. Then, the logic of
the current code will also write the third flow to 100+1.
At this time, the cache has flow 1 and 2; and the hardware FOE table
has flow 1 and 3, where these two parts store different contents.
So it is necessary to check whether the hash_val+1 is also occupied
before writing. If hash_val+1 is also occupied, we won’t bind th
third flow to the FOE table.
Addition to that, we also cancel the processing of foe_entry removal
because the hardware has auto age-out ability. The hardware will
periodically iterate through the FOE table to find out the time-out
entry and set it as INVALID.

Sometimes the tuples might be hashed to the same FOE entry.
When this hash collision problem occurs, some of the
connections will not be bound and consequently the CPU
idle rate cannot reach 100%. Therefore, two-way hashing
is adopted to alleviate this problem.

The pinmux for all SoCs using this driver is now set via the pinmux. It
makes this code obsolete.
Some of the code targeting the mt76x8 SoCs is still required. The sd
card pins share the pads with the EPHY. These pads need to be switched
to digital mode if the pins are used for sd cards.
The eMMC 8-bit mode has to be enabled via pinmux instead of a kernel
option. The uart2 group need to be set to function "sdxc d5 d4", pwm1
to "sdxc d6" and pwm0 to "sdxc d7" to do so. It can't be done by as
part of a default pinmux, as it would break the normal operation of
uart2.

To share mdio addr for IntPHY and ExtPHY,
as described in the documentation (MT7620_ProgrammingGuide.pdf).
(refer: http://download.villagetelco.org/hardware/MT7620/MT7620_ProgrammingGuide.pdf)
when port4 setup to work as gmac mode, dts like:
&gsw {
mediatek,port4 = "gmac";
};
we should set SYSCFG1.GE2_MODE==0x0 (RGMII).
but SYSCFG1.GE2_MODE may have been set to 3(RJ-45) by uboot/default
so we need to re-set it to 0x0
before this changes:
gsw: 4FE + 2GE may not work correctly and MDIO addr 4 cannot be used by ExtPHY
after this changes:
gsw: 4FE + 2GE works and MDIO addr 4 can be used by ExtPHY

When PHY's are defined on the MDIO bus in the DTS, gigabit support was
being masked out for no apparent reason, pegging all such ports to 10/100.
If gigabit support must be disabled for some reason, there should be a
"max-speed" property in the DTS.

Mediatek has a reference platform that pairs an MT7620A with an MT7530W,
where the latter responds on MDIO address 0x1f while both chips respond on
0x0 to 0x4. The driver special-cases this arrangement to make sure it's
talking to the right chip, but two different ways in two different places.
This patch consolidates the detection without the current requirement of
both tests to be separately satisfied in the DTS.

Using the NAPI or netdev frag cache along with other drivers can lead to
32 KiB pages being held for a long time, despite only being used for
very few page fragment.
This can happen if the ethernet driver grabs one or two fragments for rx
ring refill, while other drivers use (and free up) the remaining
fragments. The 32 KiB higher-order page can only be freed once all users
have freed their fragments, which only happens after the rings of all
drivers holding the fragments have wrapped around.
Depending on the traffic patterns, this can waste a lot of memory and
look a lot like a memory leak

GRO stores packets as fraglist. If they are routed back to the ethernet
device, they need to be re-segmented if the driver does not support
sending fraglists.
Add the missing support for that, along with a missing feature flag that
allows full routed GRO->TSO offload.

The mtk-mmc driver does not support access to
highmem pages, so it is really limited to the
bottom 512M (actually 448M due to 64M of IO space).
Setting ->dma_mask to NULL causes mmc_setup_queue()
