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 Calvin Johnson (15): Documentation: ACPI: DSD: Document MDIO PHY net: phy: Introduce fwnode_mdio_find_device() net: phy: Introduce phy related fwnode functions of: mdio: Refactor of_phy_find_device() net: phy: Introduce fwnode_get_phy_id() of: mdio: Refactor of_get_phy_id() net: mii_timestamper: check NULL in unregister_mii_timestamper() net: mdiobus: Introduce fwnode_mdiobus_register_phy() of: mdio: Refactor of_mdiobus_register_phy() ACPI: utils: Introduce acpi_get_local_address() net: mdio: Add ACPI support code for mdio net/fsl: Use [acpi|of]_mdiobus_register net: phylink: introduce phylink_fwnode_phy_connect() net: phylink: Refactor phylink_of_phy_connect() net: dpaa2-mac: Add ACPI support for DPAA2 MAC driver Documentation/firmware-guide/acpi/dsd/phy.rst | 133 ++++++++++++++++ MAINTAINERS | 2 + drivers/acpi/utils.c | 14 ++ .../net/ethernet/freescale/dpaa2/dpaa2-mac.c | 88 ++++++----- .../net/ethernet/freescale/dpaa2/dpaa2-mac.h | 2 +- drivers/net/ethernet/freescale/xgmac_mdio.c | 30 ++-- drivers/net/mdio/Kconfig | 14 ++ drivers/net/mdio/Makefile | 4 +- drivers/net/mdio/acpi_mdio.c | 58 +++++++ drivers/net/mdio/fwnode_mdio.c | 144 ++++++++++++++++++ drivers/net/mdio/of_mdio.c | 138 ++--------------- drivers/net/phy/mii_timestamper.c | 3 + drivers/net/phy/phy_device.c | 109 ++++++++++++- drivers/net/phy/phylink.c | 41 +++-- include/linux/acpi.h | 7 + include/linux/acpi_mdio.h | 26 ++++ include/linux/fwnode_mdio.h | 35 +++++ include/linux/phy.h | 32 ++++ include/linux/phylink.h | 3 + 19 files changed, 693 insertions(+), 190 deletions(-) create mode 100644 Documentation/firmware-guide/acpi/dsd/phy.rst create mode 100644 drivers/net/mdio/acpi_mdio.c create mode 100644 drivers/net/mdio/fwnode_mdio.c create mode 100644 include/linux/acpi_mdio.h create mode 100644 include/linux/fwnode_mdio.h
