Subject[PATCH net-next v9 00/15] ACPI support for dpaa2 driver
Date
From: Ioana Ciornei <ioana.ciornei@nxp.com>

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_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 v9:
- merged some minimal changes requested in the wording of the commit
messages
- fixed some build problems in patch 8/15 by moving the removal of
of_find_mii_timestamper from patch 8/15 to 9/15.

Changes in v8:
- fixed some checkpatch warnings/checks
- included linux/fwnode_mdio.h in fwnode_mdio.c (fixed the build warnings)
- added fwnode_find_mii_timestamper() and
fwnode_mdiobus_phy_device_register() in order to get rid of the cycle
dependency.
- change to 'depends on (ACPI || OF) || COMPILE_TEST (for FWNODE_MDIO)
- remove the fwnode_mdiobus_register from fwnode_mdio.c since it
introduces a cycle of dependencies.

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
