This driver has some exceptional cases which prevent - at the moment - its full conversion (particularly with the Autoneg bit) to using phylink_generic_validate(). Patch 1 fixes the incorrect test highlighted in the first RFC series. Patch 2 fixes the incorrect assumption that RGMII is unable to support 1000BASE-X. Patch 3 populates the supported_interfaces for each port Patch 4 removes the interface checks that become unnecessary as a result of patch 3. Patch 5 removes use of phylink_helper_basex_speed() which is no longer required by phylink. Patch 6 becomes possible after patch 5, only indicating the ethtool modes that can be supported with a particular interface mode - this involves removing some modes and adding others as per phylink documentation. Patch 7 switches the driver to use phylink_get_linkmodes(), which moves the driver as close as we can to phylink_generic_validate() due to the Autoneg bit issue mentioned above. Patch 8 converts the driver to the phylink pcs support, removing a bunch of driver private indirected methods. We include TRGMII as a PCS even though strictly TRGMII does not have a PCS. This is convenient to allow the change in patch 9 to be made. Patch 9 moves the special autoneg handling to the PCS validate method, which means we can convert the MAC side to the generic validator. Patch 10 marks the driver as non-legacy. Please review and test, thanks. drivers/net/dsa/mt7530.c | 330 +++++++++++++++++++++-------------------------- drivers/net/dsa/mt7530.h | 26 ++-- 2 files changed, 159 insertions(+), 197 deletions(-)
