There was NVMEM support added to of_get_mac_address, so it could now
return ERR_PTR encoded error values, so we need to adjust all current
users of of_get_mac_address to this new fact.
While at it, remove superfluous is_valid_ether_addr as the MAC address
returned from of_get_mac_address is always valid and checked by
is_valid_ether_addr anyway.

Several conflicts, seemingly all over the place.
I used Stephen Rothwell's sample resolutions for many of these, if not
just to double check my own work, so definitely the credit largely
goes to him.
The NFP conflict consisted of a bug fix (moving operations
past the rhashtable operation) while chaning the initial
argument in the function call in the moved code.
The net/dsa/master.c conflict had to do with a bug fix intermixing of
making dsa_master_set_mtu() static with the fixing of the tagging
attribute location.
cls_flower had a conflict because the dup reject fix from Or
overlapped with the addition of port range classifiction.
__set_phy_supported()'s conflict was relatively easy to resolve
because Andrew fixed it in both trees, so it was just a matter
of taking the net-next copy. Or at least I think it was :-)
Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup()
intermixed with changes on how the sdif and caller_net are calculated
in these code paths in net-next.
The remaining BPF conflicts were largely about the addition of the
__bpf_md_ptr stuff in 'net' overlapping with adjustments and additions
to the relevant data structure where the MD pointer macros are used.

In commit 26a4676faa1a ("arm64: mm: define NET_IP_ALIGN to 0"),
AVE controller affects this modification because the controller forces
to ignore lower 2bits of buffer start address, and make 2-byte headroom,
that is, data reception starts from (buffer + 2).
This patch defines AVE_FRAME_HEADROOM macro as hardware-specific value,
and replaces NET_IP_ALIGN with it.

If wol state of phy hardware is enabled after reset, phy_ethtool_get_wol()
returns that wol.wolopts is true.
However, since net_device.wol_enabled is zero and this doesn't apply wol
state until calling ethtool_set_wol(), so mdio_bus_phy_may_suspend()
returns true, that is, it's in a state where phy can suspend even though
wol state is enabled.
In this inconsistency, phy_suspend() returns -EBUSY, and at last,
suspend sequence fails with the following message:
dpm_run_callback(): mdio_bus_phy_suspend+0x0/0x58 returns -16
PM: Device 65000000.ethernet-ffffffff:01 failed to suspend: error -16
PM: Some devices failed to suspend, or early wake event detected
In order to fix the above issue, this patch forces to set initial wol state
to disabled as default.

There are a few MAC/PHYs combinations which now support > 1Gbps. These
may need to make use of link modes with bits > 31. Thus their
supported PHY features or advertised features cannot be implemented
using the current bitmap in a u32. Convert to using a linkmode bitmap,
which can support all the currently devices link modes, and is future
proof as more modes are added.

The driver may sleep with holding a spinlock.
The function call paths (from bottom to top) in Linux-4.17 are:
[FUNC] usleep_range
drivers/net/ethernet/socionext/sni_ave.c, 892:
usleep_range in ave_rxfifo_reset
drivers/net/ethernet/socionext/sni_ave.c, 932:
ave_rxfifo_reset in ave_irq_handler
[FUNC] usleep_range
drivers/net/ethernet/socionext/sni_ave.c, 888:
usleep_range in ave_rxfifo_reset
drivers/net/ethernet/socionext/sni_ave.c, 932:
ave_rxfifo_reset in ave_irq_handler
To fix these bugs, usleep_range() is replaced with udelay().
These bugs are found by my static analysis tool DSAC.

This patch adds support for specifying system controller that configures
phy-mode setting.
According to the DT property "phy-mode", it's necessary to configure the
controller, which is used to choose the settings of the MAC suitable,
for example, mdio pin connections, internal clocks, and so on.
Supported phy-modes are SoC-dependent. The driver allows phy-mode to set
"internal" if the SoC has a built-in PHY, and {"mii", "rmii", "rgmii"}
if the SoC supports each mode. So we have to check whether the phy-mode
is valid or not.
This adds the following features for each SoC:
- check whether the SoC supports the specified phy-mode
- configure the controller accroding to phy-mode
The DT property accepts one argument to distinguish them for multiple MAC
instances.
ethernet@65000000 {
...
socionext,syscon-phy-mode = <&soc_glue 0>;
};
ethernet@65200000 {
...
socionext,syscon-phy-mode = <&soc_glue 1>;
};

When the link is becoming up for Pro4 SoC, the kernel is stalled
due to some missing clocks and resets.
The AVE block for Pro4 is connected to the GIO bus in the SoC.
Without its clock/reset, the access to the AVE register makes the
system stall.
In the same way, another MAC clock for Giga-bit Connection and
the PHY clock are also required for Pro4 to activate the Giga-bit feature
and to recognize the PHY.
To satisfy these requirements, this patch adds support for multiple clocks
and resets, and adds the clock-names and reset-names to the binding because
we need to distinguish clock/reset for the AVE main block and the others.
Also, make the resets a required property. Currently, "reset is
optional" relies on that the bootloader or firmware has deasserted
the reset before booting the kernel. Drivers should work without
such expectation.
