net: phy: move remaining provider code to mdio_bus_provider.c

2026-03-14T19:23:02+00:00

This moves definition of mdio_bus class and bus_type to the provider side, what allows to make them private to libphy. As a prerequisite MDIO statistics handling is moved to the provider side as well. Note: This patch causes a checkpatch error "Macros with complex values should be enclosed in parentheses" for MDIO_BUS_STATS_ADDR_ATTR_GROUP. I consider this a false positive here, in addition the patch just moves existing code.

net: phy: move registering mdio_bus_class and mdio_bus_type to libphy

2026-03-14T19:23:02+00:00

The MDIO consumer side shouldn't register class and bus_type. Therefore move this to libphy. Signed-off-by: Heiner Kallweit Link: https://patch.msgid.link/b15b378a-fda2-44b9-9d63-bf82919b71b2@gmail.com Signed-off-by: Jakub Kicinski

net: phy: move (of_)mdio_find_bus to mdio_bus_provider.c

2026-03-14T19:23:02+00:00

Functionality outside libphy shouldn't access mdio_bus_class directly. So move both functions to the provider side. This is a step towards making mdio_bus_class private to libphy.

net: phy: make mdio_device.c part of libphy

2026-03-14T19:23:02+00:00

This patch - makes mdio_device.c part of libphy - makes mdio_device_(un)register_reset() static - moves mdiobus_(un)register_device() from mdio_bus.c to mdio_device.c, stops exporting both functions and makes them private to phylib This further decouples the MDIO consumer functionality from libphy. Note: This makes MDIO driver registration part of phylib, therefore adjust Kconfig dependencies where needed.
