Currently the axienet driver requires the use of a second devicetree
node, referenced by an axistream-connected attribute on the Ethernet
device node, which contains the resources for the AXI DMA block used by the
device. This setup is problematic for a use case we have where the Ethernet
and DMA cores are behind a PCIe to AXI bridge and the memory resources for
the nodes are injected into the platform devices using the multifunction
device subsystem - it's not easily possible for the driver to obtain the
platform-level resources from the linked device.
In order to simplify that usage model, and simplify the overall use of
this driver in general, allow for all of the resources to be kept on one
node where the resources are retrieved using platform device APIs rather
than device-tree-specific ones. The previous usage setup is still
supported if the axistream-connected attribute is specified.

This driver was previously using the parent node of the specified PHY
node as the device node to register the MDIO bus on. Andrew Lunn
pointed out this is wrong as the PHY node is potentially not even
underneath the MDIO bus for the current device instance. Find the MDIO
node explicitly by looking it up by name under the controller's device
node instead.
This could potentially break existing device trees if they don't use
"mdio" as the name for the MDIO bus, but I did not find any with various
searches and Xilinx's examples all use mdio as the name so it seems like
this should be relatively safe.

On some platforms, such as iMX6 with PCIe devices, crashes or hangs can
occur if the axienet device continues to perform DMA transfers after
parent devices/busses have been shut down. Shut down the axienet

It is possible that the interrupt handler fires and frees up space in
the TX ring in between checking for sufficient TX ring space and
stopping the TX queue in axienet_start_xmit. If this happens, the
queue wake from the interrupt handler will occur before the queue is
stopped, causing a lost wakeup and the adapter's transmit hanging.
To avoid this, after stopping the queue, check again whether there is
sufficient space in the TX ring. If so, wake up the queue again.

Previously this driver only handled interrupts from the DMA RX and TX
blocks, not from the Ethernet core itself. Add optional support for
the Ethernet core interrupt, which is used to detect rx_missed and
framing errors signalled by the hardware. In order to use this
interrupt, a third interrupt needs to be specified in the device tree.

The Xilinx DMA blocks each have their own reset register, but they both
reset the entire DMA engine, so only one of them needs to be reset.
Also, when stopping the device, we need to not just command the DMA
blocks to stop, but wait for them to stop, and trigger a device reset
to ensure that they are completely stopped.

The MDIO clock divisor register setting was only applied on the initial
startup when the driver was loaded. However, this setting is cleared
when the device is reset, such as would occur when the interface was
taken down and brought up again, and so the MDIO bus would be
non-functional afterwards.
Split up the MDIO bus setup and enable into separate functions and
re-enable the bus after a device reset, to ensure that the MDIO
registers are set properly. This also allows us to remove direct access
to MDIO registers in xilinx_axienet_main.c and centralize them all in
xilinx_axienet_mdio.c.
Also, lock the MDIO bus lock around the device reset process, to avoid
MDIO accesses from occurring while the MDIO is disabled during the reset.

This driver was previously always calculating the MDIO clock divisor
(from AXI bus clock to MDIO bus clock) based on the CPU clock frequency,
assuming that it is the same as the AXI bus frequency, but that
simplistic method only works on the MicroBlaze platform.
Add support for specifying the clock used for the device in the device
tree using the clock framework. If the clock is specified then it will
be used when calculating the clock divisor. The previous CPU clock
detection method is left for backward compatibility if no clock is

- The emac PHY setup bits are in separate registers.
- The PTP reference clock select mask is different.
- The register to enable the emac signal from FPGA is different.

WoL magic packet configuration sometimes does not work due to
couple of leakages found.
Mainly there was a regression introduced during readx_poll refactoring.
Next, fw request waiting time was too small. Sometimes that
caused sleep proxy config function to return with an error
and to skip WoL configuration.
At last, WoL data were passed to FW from not clean buffer.
That could cause FW to accept garbage as a random configuration data.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct nfp_tun_active_tuns {
...
struct route_ip_info {
__be32 ipv4;
__be32 egress_port;
__be32 extra[2];
} tun_info[];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(struct nfp_tun_active_tuns) + sizeof(struct route_ip_info) * count
with:
struct_size(payload, tun_info, count)

Similar to the X540 hardware, enable support for generating a 1pps
output signal on SDP0.
This support is slightly different to the X540 hardware, because of the
register layout changes. First, the system time register is now
represented in 'cycles' and 'billions of cycles'. Second, we need to
also program the TSSDP register, as well as the ESDP register. Third,
the clock output uses only FREQOUT, instead of a full 64bit value for
the output clock period. Finally, we have to use the ST0 bit instead of
the SYNCLK bit in the TSAUXC register.
This support should work even for the hardware with a higher frequency
clock, as it carefully takes into account the multiply and shift of the
cycle counter used.
We also set the pps configuration to 1, since we now support generating
a pulse per second output.
