    net/designware - switch driver to phylib usage · 92a190aa
    Alexey Brodkin authored
    With this change driver will benefit from existing phylib and thus
    custom phy functionality implemented in the driver will go away:
     * Instantiation of the driver is now much shorter - 2 parameters
    instead of 4.
     * Simplified phy management/functoinality in driver is replaced with
    rich functionality of phylib.
     * Support of custom phy initialization is now done with existing
    "board_phy_config".
    
    Note that after this change some previously used config options
    (driver-specific PHY configuration) will be obsolete and they are simply
    substituted with similar options of phylib.
    
    For example:
     * CONFIG_DW_AUTONEG - no need in this one. Autonegotiation is enabled
    by default.
     * CONFIG_DW_SEARCH_PHY - if one wants to specify attached phy
    explicitly CONFIG_PHY_ADDR board config option has to be used, otherwise
    automatically the first discovered on MDIO bus phy will be used
    
    I believe there's no need now in "doc/README.designware_eth" because
    user only needs to instantiate the driver with "designware_initialize"
    whose prototype exists in "include/netdev.h".
