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.

net: phy: move mdio_device reset handling functions in the code

In preparation of a follow-up patch this moves reset-related functions in the code. Signed-off-by: Heiner Kallweit Link: https://patch.msgid.link/8ea1a929-33b8-49ee-afe6-355f5a7d2bd1@gmail.com Signed-off-by: Jakub Kicinski

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

net: phy: remove modalias-based mdio bus matching

2026-02-03T11:46:55+00:00

Last user dsa_loop has been migrated away from modalias-based matching, so we can remove this feature now. It was the only user of MDIO_NAME_SIZE, so remove also this constant.

net: mdio: improve reset handling in mdio_device.c

2025-11-21T01:41:39+00:00

Change fwnode_property_read_u32() in mdio_device_register_reset() to device_property_read_u32(), which is more appropriate here. Make mdio_device_unregister_reset() truly reverse mdio_device_register_reset() by setting the internal fields to their default values.

net: mdio: common handling of phy device reset properties

2025-11-21T01:41:39+00:00

Unify the handling of the per device reset properties for `mdio_device`. Merge mdio_device_register_gpiod() and mdio_device_register_reset() into mdio_device_register_reset(), that handles both reset-controllers and reset-gpios. Move reading of the reset firmware properties (reset-assert-us, reset-deassert-us) from fwnode_mdio.c to mdio_device_register_reset(), so all reset related initialization code is kept in one place. Introduce mdio_device_unregister_reset() to release the associated resources. These changes make tracking the reset properties easier. Added kernel-doc for mdio_device_register/unregister_reset().

net: mdio: move device reset functions to mdio_device.c

2025-11-21T01:41:39+00:00

The functions mdiobus_register_gpiod() and mdiobus_register_reset() handle the mdio device reset initialization, which belong to mdio_device.c. Move them from mdio_bus.c to mdio_device.c, and rename them to match the corresponding source file: mdio_device_register_gpio() and mdio_device_register_reset(). Remove 'static' qualifiers and declare them in drivers/net/phy/mdio-private.h (new header file).

net: phy: assign default match function for non-PHY MDIO devices

2025-06-13T01:12:37+00:00

Make mdio_device_bus_match() the default match function for non-PHY MDIO devices. Benefit is that we don't have to export this function any longer. As long as mdiodev->modalias isn't set, there's no change in behavior. mdiobus_create_device() is the only place where mdiodev->modalias gets set, but this function sets mdio_device_bus_match() as match function anyway.
