This part of the series focuses on the generic PHY driver, but these changes have dependencies on the ethernet driver, hence why it will need to go via net-next. Furthermore, subsequent changes depend on these patches. The underlying ideas here are: - get rid of the driver using phy_set_speed() with SPEED_1000 and SPEED_2500 which makes no sense for an ethernet SerDes due to the PCS 8B10B data encoding, which inflates the data rate at the SerDes compared to the MAC. This is replaced with phy_set_mode_ext(). - allow phy_power_on() / phy_set_mode*() to be called in any order. Mohd has tested this series, although not in the resulting merge order. Changes since resend2: - Drop patch 2 as that is now applied - Add Vinod's Acks, which were eventually sent in response to the first posting of this series. .../ethernet/stmicro/stmmac/dwmac-qcom-ethqos.c | 31 +++------ drivers/phy/qualcomm/phy-qcom-sgmii-eth.c | 73 ++++++++++------------ 2 files changed, 41 insertions(+), 63 deletions(-) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
