[PATCH 1/5] dt-bindings: net: ipq4019-mdio: document IPQ6018 compatible

[PATCH 1/5] dt-bindings: net: ipq4019-mdio: document IPQ6018 compatible

[Robert Marko]

Document IPQ6018 compatible that is already being used in the DTS along
with the fallback IPQ4019 compatible as driver itself only gets probed
on IPQ4019 and IPQ5018 compatibles.

This is also required in order to specify which platform require clock to
be defined and validate it in schema.

[PATCH 2/5] dt-bindings: net: ipq4019-mdio: add IPQ8074 compatible

[Robert Marko]

Allow using IPQ8074 specific compatible along with the fallback IPQ4019
one in order to be able to specify which compatibles require clocks to
be able to validate them via schema.

[PATCH 3/5] dt-bindings: net: ipq4019-mdio: require and validate clocks

[Robert Marko]

Now that we can match the platforms requiring clocks by compatible start
using those to allow clocks per compatible and make them required.

[PATCH 4/5] dt-bindings: net: ipq4019-mdio: document required clock-names

[Robert Marko]

IPQ5018, IPQ6018 and IPQ8074 require clock-names to be set as driver is
requesting the clock based on it and not index, so document that and make
it required for the listed SoC-s.

Similarly to clocks, define clock-names in top-level and disallow them
for other variants. Do not define properties in allOf:if:then - it makes
schema difficult to maintain and read.
