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. v3 of this series arrived too close to the end of the last development cycle and was deferred, hence this respin on top of current net-next. --- v4: * rebase onto current net-next * 5/8: zero the read-back buffer in mt7530_regmap_read() instead of initialising the result variables at every call site, as suggested by Jakub * 6/8: keep MT753X_CTRL_PHY_ADDR() as plain address arithmetic rather than converting it to FIELD_PREP() as suggested in review: the macro computes the MDIO bus address of the switch PHYs, used as the addr argument of bus->read/write and as an iterator base in mt7530_setup_mdio(), not a hardware register field v3: * 5/8: initialise register read-back variables to 0 so a failed regmap_read keeps the previous read-as-zero behaviour, and use u32 for the value in mt7530_setup_port5 * 6/8: name the age timer field AGE_TIMER_MASK and document the corrected ATC_HASH/VTCR_VID field macros * 7/8: serialise the port_fast_age ATC flush under reg_mutex and log on timeout, align a define, and correct the commit message which wrongly claimed per-port parity with b53/realtek * 8/8: populate the netlink extack on rejection and refuse a conduit that lives on a different switch v2: * fix stray 'static void' left-over in 4/8 which had a fix accidentally folded into 5/8 (byte-identical state at 8/8, but bisectability is restored) * extend port_change_conduit op commit message Daniel Golle (8): net: dsa: mt7530: move MDIO bus locking into regmap net: dsa: mt7530: fold mt7530_mii_write/read into mt7530_write/read net: dsa: mt7530: replace mt7530_write with regmap_write net: dsa: mt7530: replace mt7530_rmw/set/clear with regmap API net: dsa: mt7530: replace mt7530_read with regmap_read net: dsa: mt7530: convert to use field accessor macros net: dsa: mt7530: implement port_fast_age net: dsa: mt7530: implement port_change_conduit op drivers/net/dsa/mt7530-mdio.c | 12 +- drivers/net/dsa/mt7530.c | 809 +++++++++++++++++----------------- drivers/net/dsa/mt7530.h | 209 +++++---- 3 files changed, 537 insertions(+), 493 deletions(-) base-commit: ce6b4d3216b63f902bb8e9695ee6c10c83415f65 -- 2.55.0
