Merge branch 'dt-bindings-net-mdio.yaml-fixes'
Florian Fainelli says:
====================
dt-bindings: net: mdio.yaml fixes
This patch series documents some common MDIO devices properties such as
resets (and delays) and broken-turn-around. The second patch also
rephrases some descriptions to be more general towards MDIO devices and
not specific towards Ethernet PHYs.
Changes in v3:
- corrected wording of 'broken-turn-around' in ethernet-phy.yaml and
mdio.yaml, add Andrew's R-b tag to patch #3
