[net-next PATCH v4 00/15] ACPI support for dpaa2 driver

[Calvin Johnson]

This patch set provides ACPI support to DPAA2 network drivers.

It also introduces new fwnode based APIs to support phylink and phy
layers
    Following functions are defined:
      phylink_fwnode_phy_connect()
      fwnode_mdiobus_register_phy()
      fwnode_mdiobus_register()
      fwnode_get_phy_id()
      fwnode_phy_find_device()
      device_phy_find_device()
      fwnode_get_phy_node()
      fwnode_mdio_find_device()
      fwnode_get_id()

    First one helps in connecting phy to phylink instance.
    Next three helps in getting phy_id and registering phy to mdiobus
    Next two help in finding a phy on a mdiobus.
    Next one helps in getting phy_node from a fwnode.
    Last one is used to get fwnode ID.

    Corresponding OF functions are refactored.

Tested-on: LS2088ARDB and LX2160ARDB


Changes in v4:
- More cleanup
- Improve code structure to handle all cases
- Remove redundant else from fwnode_mdiobus_register()
- Cleanup xgmac_mdio_probe()
- call phy_device_free() before returning

Changes in v3:
- Add more info on legacy DT properties "phy" and "phy-device"
- Redefine fwnode_phy_find_device() to follow of_phy_find_device()
- Use traditional comparison pattern
- Use GENMASK
- Modified to retrieve reg property value for ACPI as well
- Resolved compilation issue with CONFIG_ACPI = n
- Added more info into documentation
- Use acpi_mdiobus_register()
- Avoid unnecessary line removal
- Remove unused inclusion of acpi.h

Changes in v2:
- Updated with more description in document
- use reverse christmas tree ordering for local variables
- Refactor OF functions to use fwnode functions
