Hi, This is another attempt to move the mv88e6xxx driver forward so that we can eventually switch it to use phylink_pcs and become a non-legacy driver. The issue is that in order to switch to phylink_pcs, we need DSA and CPU ports to be known to phylink, otherwise the PCS code will not be called. In order for such ports to be known to phylink, we need to provide phylink with a configuration, and mv88e6xxx has a history of not specifying the configuration in firmware, but the driver internally handling that. This is fine, but it means we can't use phylink for such ports - and thus converting them to phylink_pcs can cause regressions. Therefore, this series provides a way for a software-node configuration to be provided to DSA by the driver, which will then be used only for phylink to parse. Some of this patch set comes from an idea from Vladimir, but re-implemented in a substantially different way. drivers/base/swnode.c | 14 +++- drivers/net/dsa/mv88e6xxx/chip.c | 157 ++++++++++++++++++++++++++++----------- drivers/net/phy/phylink.c | 32 ++++++++ include/linux/phylink.h | 1 + include/linux/property.h | 4 + include/net/dsa.h | 3 + net/dsa/port.c | 33 ++++++-- 7 files changed, 191 insertions(+), 53 deletions(-) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
