This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,

This adds the driver for the IPQ40xx built-in MDIO.
This will be needed to support future PHY driver.
Signed-off-by: Robert Marko <robert.marko@sartura.hr>
Cc: Luka Perkov <luka.perkov@sartura.hr>
When sending a command via the MDIO bus, the Designware MAC expects some
bits in the CMD register to describe the clock divider value between
the main clock and the MDIO clock.
So far we were omitting these bits, resulting in setting "00", which
means "/ 16", so ending up with an MDIO frequency of either 18.75 or
12.5 MHz.
All the internal PHYs in the H3/H5/H6 SoCs as well as the Gbit Realtek
PHYs seem to be fine with that - although it looks like to be severly
overclocked (the MDIO spec limits the frequency to 2.5 MHz).
However the external 100Mbit PHY on the Pine64 (non-plus) board is
not happy with that, Ethernet was actually never working there, as the
PHY didn't probe.
As we set the EMAC clock (via AHB2) to 300 MHz in ATF (on the 64-bit
SoCs), and use 200 MHz on the H3, we need the highest divider of 128
to let the MDIO clock end up below the required 2.5 MHz.
This enables Ethernet on the Pine64(non-plus).

The current implementation of sun8i_get_ephy_nodes() makes quite some
assumptions, in general relying on DT path names is a bad idea.
I think the idea of the code was to determine if we are using the
internal PHY, for which there are simpler and more robust methods:
Rewrite (and rename) the existing function to simply lookup the DT node
that "phy-handle" points to, using the device's DT node.
Then check whether the parent of that PHY node is using an "H3 internal
MDIO" compatible string. If we ever get another internal MDIO bus
implementation, we will probably need code adjustments anyway, so this
is good enough for now.

The error handling in recv() is somewhat broken, for instance
good_packet isn't really used, and it's hardly readable. Also we try
to check for short or too big packets, but those are actually filtered
out by the hardware.
Simplify the whole routine and improve the error handling:
- Bail out early if the current RX descriptor is not ready.
- Enable propagation of runt, huge and broken packets.
- Check for runt and huge packets, and return 0 to indicate this.
This will force the framework to call free_pkt for cleanup.
- Avoid aligning the packet buffer for invalidation again.

When initialising the TX DMA descriptors, we mostly chain them up,

That means they are still invalid, and the OWN bit should NOT be set

In fact when we later tell the MAC about the beginning of the chain,
and enable TX DMA in the start() routine, the MAC will start fetching
TX descriptors prematurely, as it can be seen by dumping the TX_DMA_STA
and TX_DMA_CUR_DESC registers.

- 2.0 ns (which causes the data to be sampled at exactly half way between
clock transitions at 1000 Mbps) if delays should be enabled
depending on the interface mode
