[PATCH v2 net-next 0/4] Convert NXP SJA1105 DSA driver to YAML

[Vladimir Oltean <olteanv@gmail.com>]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

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.

Vladimir Oltean (4):
  net: phy: introduce PHY_INTERFACE_MODE_REVRMII
  net: dsa: sja1105: apply RGMII delays based on the fixed-link property
  net: dsa: sja1105: determine PHY/MAC role from PHY interface type
