Subject: [PATCH net-next v2 0/2] net: stmmac: Add support for coarse timestamping

Hello everyone,

This is V2 for coarse timetamping support in stmmac. This version uses a
dedicated devlink param "ts_coarse" to control this mode.

This doesn't conflict with Russell's cleanup of hwif.

[1] : https://lore.kernel.org/netdev/20200514102808.31163-1-olivier.dautricourt@orolia.com/

Changes in V2:
 - Use devlink intead of tsconfig
 - Rebase on top of Russell's rework of has_xxx flags

V1: https://lore.kernel.org/netdev/20251015102725.1297985-1-maxime.chevallier@bootlin.com/
