Jakub Kicinski 795eb0feb4 Merge branch 'net-dsa-mt7530-modernise-register-access-and-add-two-dsa-ops'
Daniel Golle says:

====================
net: dsa: mt7530: modernise register access and add two DSA ops

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.
The two remaining reset polls are converted to
regmap_read_poll_timeout() and the then-unused dummy poll machinery is
dropped. Open-coded register fields are 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.

The swallowed MDIO errors Sashiko flagged on v4 5/8 have meanwhile been
fixed in tree by "fix swallowed MDIO read errors" and "fix remaining
swallowed MDIO access errors", both merged into net-next. This respin is
rebased on top of them: regmap_* return values are no longer ignored,
which is what most of the semantic patches had to be reworked for.
