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
