This series is the next of the three part series sorting out the PCS support in stmmac, building on part 2: net: stmmac: qcom-ethqos: further serdes reorganisation Similar patches have been posted previously. This series does away with the common SerDes PHY support, instead using a flag to indicate whether 2500Mbps mode is supported (STMMAC_FLAG_SERDES_SUPPORTS_2500M.) At this time, I have no plans to resurect the common SerDes PHY support - the generic PHY layer implementations are just too random to consider that, and I certainly do not want the extra work of fixing that. Changes from RFC v3: - only set default_an_inband if using SGMII/2500BASE-X mode. drivers/net/ethernet/stmicro/stmmac/common.h | 4 - .../ethernet/stmicro/stmmac/dwmac-qcom-ethqos.c | 2 + drivers/net/ethernet/stmicro/stmmac/dwmac1000.h | 12 +- .../net/ethernet/stmicro/stmmac/dwmac1000_core.c | 11 +- drivers/net/ethernet/stmicro/stmmac/dwmac4.h | 10 +- drivers/net/ethernet/stmicro/stmmac/dwmac4_core.c | 10 +- drivers/net/ethernet/stmicro/stmmac/stmmac_main.c | 8 +- drivers/net/ethernet/stmicro/stmmac/stmmac_pcs.c | 156 +++++++++++++++++++-- drivers/net/ethernet/stmicro/stmmac/stmmac_pcs.h | 29 +++- include/linux/stmmac.h | 1 + 10 files changed, 197 insertions(+), 46 deletions(-) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
