    stmmac: unify MAC and PHY configuration parameters (V2) · 36bcfe7d
    Giuseppe CAVALLARO authored
    Prior to this change, most PHY configuration parameters were passed
    into the STMMAC device as a separate PHY device. As well as being
    unusual, this made it difficult to make changes to the MAC/PHY
    relationship.
    
    This patch moves all the PHY parameters into the MAC configuration
    structure, mainly as a separate structure. This allows us to completely
    ignore the MDIO bus attached to a stmmac if desired, and not create
    the PHY bus. It also allows the stmmac driver to use a different PHY
    from the one it is connected to, for example a fixed PHY or bit banging
    PHY.
    
    Also derive the stmmac/PHY connection type (MII/RMII etc) from the
    mode can be passed into <platf>_configure_ethernet.
    STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git
    provides several examples how to use this new infrastructure (that
    actually is easier to maintain and clearer).
