    net: phy: remove PM ops from MDIO bus · 9107c05e
    Heiner Kallweit authored
    Current implementation of MDIO bus PM ops doesn't actually implement
    bus-specific PM ops but just calls PM ops defined on a device level
    what doesn't seem to be fully in line with the core PM model.
    When looking e.g. at __device_suspend() the PM core looks for PM ops
    of a device in a specific order:
    1. device PM domain
    2. device type
    3. device class
    4. device bus
    I think it has good reason that there's no PM ops on device level.
    Now that a device type representation of PHY's as special type of MDIO
    devices was added (only user of MDIO bus PM ops), the MDIO bus
    PM ops can be removed including member pm of struct mdio_device.
    If for some other type of MDIO device PM ops are needed, it should be
    modeled as struct device_type as well.
