[PATCH net-next 0/8] net: dsa: mt7530: modernise register access and add two DSA ops

[Daniel Golle]

The mt7530 driver carries its own register accessors that predate the
regmap conversion and now largely duplicate what regmap already
provides, including locking. Most of this series removes that layer.

It first moves the MDIO bus locking into the switch regmap via
.lock/.unlock callbacks, matching the PCS regmaps, so any path reaching
the regmap is serialised automatically. With the wrappers no longer
adding locking, the thin mt7530_mii_* indirection is folded away and the
remaining accessors are replaced mechanically with the plain regmap API,
using the coccinelle semantic patches included in the commit messages.
Open-coded register fields are then converted to FIELD_GET/FIELD_PREP.
None of this is intended to change behaviour.

The last two patches implement .port_fast_age, which flushes dynamically
learned MAC entries on topology changes, and .port_change_conduit, which
moves a user port's CPU-port affinity at runtime.
