Introduce fwnode_mdiobus_register() to register PHYs on the mdiobus. If the fwnode is DT node, then call of_mdiobus_register(). If it is an ACPI node, then call acpi_mdiobus_register(). Signed-off-by: Calvin Johnson <redacted> --- Changes in v7: - Move fwnode_mdiobus_register() to fwnode_mdio.c Changes in v6: None Changes in v5: None Changes in v4: - Remove redundant else from fwnode_mdiobus_register() Changes in v3: - Use acpi_mdiobus_register() Changes in v2: None drivers/net/mdio/fwnode_mdio.c | 21 +++++++++++++++++++++ include/linux/fwnode_mdio.h | 5 +++++ 2 files changed, 26 insertions(+)
