As the code derives straight from of_mdio.c, there is absolutely no deviation from Documentation/devicetree/bindings/net/mdio.txt. > > How does documentation work in the ACPI world? > ACPI has its own specification, the newest one is 6.2 http://www.uefi.org/sites/default/files/resources/ACPI_6_2.pdf It is pretty likely, that if we establish a generic solution for the MDIO bus, a short section about it may probably require adding to above - for now I see none.
