From 62a6ef6a996f5eec73d30d079573a1fa8f95fcd9 Mon Sep 17 00:00:00 2001 From: Marcin Wojtas Date: Mon, 21 Jun 2021 19:30:24 +0200 Subject: net: mdiobus: Introduce fwnode_mdbiobus_register() This patch introduces a new helper function that wraps acpi_/of_ mdiobus_register() and allows its usage via common fwnode_ interface. Fall back to raw mdiobus_register() in case CONFIG_FWNODE_MDIO is not enabled, in order to satisfy compatibility in all future user drivers. Signed-off-by: Marcin Wojtas Signed-off-by: David S.
