Subject: [net-next PATCH v7 00/16] ACPI support for dpaa2 driver
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()
acpi_get_local_address()
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 local address from _ADR object.
Corresponding OF functions are refactored.
Tested-on: LX2160ARDB
Changes in v7:
- correct fwnode_mdio_find_device() description
- check NULL in unregister_mii_timestamper()
- Call unregister_mii_timestamper() without NULL check
- Create fwnode_mdio.c and move fwnode_mdiobus_register_phy()
- include fwnode_mdio.h
- Include headers directly used in acpi_mdio.c
- Move fwnode_mdiobus_register() to fwnode_mdio.c
- Include fwnode_mdio.h
- Alphabetically sort header inclusions
- remove unnecassary checks
Changes in v6:
- Minor cleanup
- fix warning for function parameter of fwnode_mdio_find_device()
- Initialize mii_ts to NULL
- use GENMASK() and ACPI_COMPANION_SET()
- some cleanup
- remove unwanted header inclusion
- remove OF check for fixed-link
- use dev_fwnode()
- remove useless else
- replace of_device_is_available() to fwnode_device_is_available()
Changes in v5:
- More cleanup
- Replace fwnode_get_id() with acpi_get_local_address()
- add missing MODULE_LICENSE()
- replace fwnode_get_id() with OF and ACPI function calls
- replace fwnode_get_id() with OF and ACPI function calls
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
