json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Scripted with ruamel.yaml with some manual fixups. Some minor whitespace changes from the script.

The property is identical to 'phy-mode', and assumes that there is mode

converter in-between the MAC & PHY (e.g. GMII-to-RGMII). This converter

can be passive (no SW requirement), and requires that the MAC operate
|
|
in a different mode than the PHY in order to function.
