The controller is a little unique in that we can't access the= SMI interfaces directly. This means we need to use the hardware description f= rom the DTS to compute a mapping of switch port to mdio bus/address. Note that the dt-bindings: mfd patch is dependent on the dt-bindings: net= patch. Gmail seems to have decided to throttle mail coming from our domain so th= ere has been some things I've responded to that have hit lore.kernel.org but = may not have been delivered directly. So sorry if it looks like I've ignored something. That's also why I haven't send this round out earlier as hopef= ully we've done enough to get of Google's naughty list.
