    mfd: lochnagar: Add support for the Cirrus Logic Lochnagar · 422dcafe
    Charles Keepax authored
    Lochnagar is an evaluation and development board for Cirrus
    Logic Smart CODEC and Amp devices. It allows the connection of
    most Cirrus Logic devices on mini-cards, as well as allowing
    connection of various application processor systems to provide a
    full evaluation platform. This driver supports the board
    controller chip on the Lochnagar board. Audio system topology,
    clocking and power can all be controlled through the Lochnagar
    controller chip, allowing the device under test to be used in
    a variety of possible use cases.
    
    As the Lochnagar is a fairly complex device this MFD driver
    allows the drivers for the various features to be bound
    in. Initially clocking, regulator and pinctrl will be added as
    these are necessary to configure the system. But in time at least
    audio and voltage/current monitoring will also be added.
