====================
Convert NXP SJA1105 DSA driver to YAML

This is an attempt to convert the SJA1105 driver to the YAML schema.

The SJA1105 driver has some custom device tree properties which caused
validation problems in the previous attempt:
https://patchwork.kernel.org/project/netdevbpf/patch/20210531234735.1582031-1-olteanv@gmail.com/

So now we are removing them, hoping that this will make the conversion
easier to accept.

In order to do that, we introduce a new PHY interface type, "reverse RMII",
which is like "reverse MII" (aka MII as a PHY) but for the reduced data
width version of the protocol. This is a direct replacement for an rmii
fixed-link. Now, rmii fixed-link interfaces behave as a MAC, and rev-rmii
fixed-link interfaces behave as a PHY.
====================

Since the sja1105 driver no longer has any custom device tree

Now that both RevMII as well as RevRMII exist, we can deprecate the
sja1105,role-mac and sja1105,role-phy properties and simply let the user
select that a port operates in MII PHY role by using
	phy-mode = "rev-mii";
or in RMII PHY role by using
	phy-mode = "rev-rmii";

There are no fixed-link MII or RMII properties in mainline device trees,
and the setup itself is fairly uncommon, so there shouldn't be risks of
breaking compatibility.

The sja1105 driver has an intermediate way of determining whether the
RGMII delays should be applied by the PHY or by itself: by looking at
the port role (PHY or MAC). The port can be put in the PHY role either
explicitly (sja1105,role-phy) or implicitly (fixed-link).

We want to deprecate the sja1105,role-phy property, so all that remains
is the fixed-link property. Introduce a "fixed_link" array of booleans
in the driver, and use that to determine whether RGMII delays must be
applied or not.

The "reverse RMII" protocol name is a personal invention, derived from
"reverse MII".

Just like MII, RMII is an asymmetric protocol in that a PHY behaves
differently than a MAC. In the case of RMII, for example:
- the 50 MHz clock signals are either driven by the MAC or by an
  external oscillator (but never by the PHY).
- the PHY can transmit extra in-band control symbols via RXD[1:0] which
  the MAC is supposed to understand, but a PHY isn't.

The "reverse MII" protocol is not standardized either, except for this
web document:
https://www.eetimes.com/reverse-media-independent-interface-revmii-block-architecture/#

In short, it means that the Ethernet controller speaks the 4-bit data
parallel protocol from the perspective of a PHY (it acts like a PHY).
This might mean that it implements clause 22 compatible registers,
although that is optional - the important bit is that its pins can be
connected to an MII MAC and it will 'just work'.

In this discussion thread:
https://lore.kernel.org/netdev/20210201214515.cx6ivvme2tlquge2@skbuf/

we agreed that it would be an abuse of terms to use the "RevMII" name
for anything than the 4-bit parallel MII protocol. But since all the
same concepts can be applied to the 2-bit Reduced MII protocol as well,
here we are introducing a "Reverse RMII" protocol. This means: "behave
like an RMII PHY".
