The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

64-bit DMA detection will fail if axienet was started before (by boot
loader, boot ROM, etc). In this state axienet will not start properly.
XAXIDMA_TX_CDESC_OFFSET + 4 register (MM2S_CURDESC_MSB) is used to detect
64-bit DMA capability here. But datasheet says: When DMACR.RS is 1
(axienet is in enabled state), CURDESC_PTR becomes Read Only (RO) and
is used to fetch the first descriptor. So iowrite32()/ioread32() trick
to this register to detect 64-bit DMA will not work.
So move axienet reset before 64-bit DMA detection.

It is not allowed to call kfree_skb() or consume_skb() from hardware
interrupt context or with hardware interrupts being disabled.
It should use dev_kfree_skb_irq() or dev_consume_skb_irq() instead.
The difference between them is free reason, dev_kfree_skb_irq() means
the SKB is dropped in error and dev_consume_skb_irq() means the SKB
is consumed in normal.
In this case, dev_kfree_skb() is called in xemaclite_tx_timeout() to
drop the SKB, when tx timeout, so replace it with dev_kfree_skb_irq().

Some FPGA platforms have 80KHz MDIO bus frequency constraint when
connecting Ethernet to its on-board external Marvell PHY. Thus, we may
have to set MDIO clock according to the DT. Otherwise, use the default
2.5 MHz, as specified by 802.3, if the entry is not present.
Also, change MAX_MDIO_FREQ to DEFAULT_MDIO_FREQ because we may actually
set MDIO bus frequency higher than 2.5MHz if undelying devices support
it. And properly disable the mdio bus clock in error path.

so lets remove the necessity for network drivers to explicitly set

According to commit f735c40ed93c ("net: axienet: Autodetect 64-bit DMA
capability") and AXI-DMA spec (pg021), on 64-bit capable dma, only
writing MSB part of tail descriptor pointer causes DMA engine to start
fetching descriptors. However, we found that it is true only if dma is in
idle state. In other words, dma would use a tailp even if it only has LSB
updated, when the dma is running.
The non-atomicity of this behavior could be problematic if enough
delay were introduced in between the 2 writes. For example, if an
interrupt comes right after the LSB write and the cpu spends long
enough time in the handler for the dma to get back into idle state by
completing descriptors, then the seconcd write to MSB would treat dma
to start fetching descriptors again. Since the descriptor next to the
one pointed by current tail pointer is not filled by the kernel yet,
fetching a null descriptor here causes a dma internal error and halt
the dma engine down.
We suggest that the dma engine should start process a 64-bit MMIO write
to the descriptor pointer only if ONE 32-bit part of it is written on all
states. Or we should restrict the use of 64-bit addressable dma on 32-bit
platforms, since those devices have no instruction to guarantee the write
to LSB and MSB part of tail pointer occurs atomically to the dma.
initial condition:
curp = x-3;
tailp = x-2;
LSB = x;
MSB = 0;
cpu: |dma:
iowrite32(LSB, tailp) | completes #(x-3) desc, curp = x-3
... | tailp updated

Currently it is not safe to config the IP as 64-bit addressable on 32-bit
archectures, which cannot perform a double-word store on its descriptor
pointers. The pointer is 64-bit wide if the IP is configured as 64-bit,
and the device would process the partially updated pointer on some
states if the pointer was updated via two store-words. To prevent such
condition, we force a probe fail if we discover that the IP has 64-bit
capability but it is not running on a 64-Bit kernel.
This is a series of patch (1/2). The next patch must be applied in order
to make 64b DMA safe on 64b archectures.

This driver was using the TX IRQ handler to perform all TX completion
tasks. Under heavy TX network load, this can cause significant irqs-off
latencies (found to be in the hundreds of microseconds using ftrace).
This can cause other issues, such as overrunning serial UART FIFOs when
using high baud rates with limited UART FIFO sizes.
Switch to using a NAPI poll handler to perform the TX completion work
to get this out of hard IRQ context and avoid the IRQ latency impact.
A separate poll handler is used for TX and RX since they have separate
IRQs on this controller, so that the completion work for each of them
stays on the same CPU as the interrupt.
Testing on a Xilinx MPSoC ZU9EG platform using iperf3 from a Linux PC
through a switch at 1G link speed showed no significant change in TX or
RX throughput, with approximately 941 Mbps before and after. Hard IRQ
time in the TX throughput test was significantly reduced from 12% to
below 1% on the CPU handling TX interrupts, with total hard+soft IRQ CPU
usage dropping from about 56% down to 48%.

The axienet_start_xmit function was updating the tx_bd_tail variable
multiple times, with potential rollbacks on error or invalid
intermediate positions, even though this variable is also used in the
TX completion path. Use READ_ONCE where this variable is read and
WRITE_ONCE where it is written to make this update more atomic, and
move the write before the MMIO write to start the transfer, so it is
protected by that implicit write barrier.

In some SGMII use cases where both a fixed link external PHY and the

phandle "pcs-phy" to get the reference to the PCS/PMA PHY. Otherwise, the
driver would use "phy-handle" in the DT as the reference to both the
external and the internal PCS/PMA PHY.
In other cases where the core is connected to a SFP cage, we could still
point phy-handle to the intenal PCS/PMA PHY, and let the driver connect
to the SFP module, if exist, via phylink.

the struct member `phy_node` of struct axienet_local is not used by the
driver anymore after initialization. It might be a remnent of old code
and could be removed.

The call to axienet_mdio_setup should not depend on whether "phy-node"
pressents on the DT. Besides, since `lp->phy_node` is used if PHY is in
SGMII or 100Base-X modes, move it into the if statement. And the next patch
will remove `lp->phy_node` from driver's private structure and do an
of_node_put on it right away after use since it is not used elsewhere.

Use napi_alloc_skb to allocate memory when refilling the RX ring
in axienet_poll for more efficiency. napi_alloc_skb() can reuse
softirq-local cache of freed skbs which may still be cache-warm
and skipping allocator calls.

This node pointer is returned by of_parse_phandle() with refcount
incremented in this function. Calling of_node_put() to avoid the
refcount leak. As the remove function do.

Add the ability to configure the RX/TX coalesce timer with ethtool.
Change default setting to scale with the clock rate rather than being a
fixed number of clock cycles.
