    regulator: core: Parse coupled regulators properties · a085a31a

    On Odroid XU3/4 and other Exynos5422 based boards there is a case, that
    different devices on the board are supplied by different regulators
    with non-fixed voltages. If one of these devices temporarily requires
    higher voltage, there might occur a situation that the spread between
    devices' voltages is so high, that there is a risk of changing
    'high' and 'low' states on the interconnection between devices powered
    by those regulators.
    Add new structure "coupling_desc" to regulator_dev, which contains
    pointers to all coupled regulators including the owner of the structure,
    number of coupled regulators and counter of currently resolved
    Add of_functions to parse all data needed in regulator coupling.
    Provide method to check DTS data consistency. Check if each coupled
    regulator's max_spread is equal and if their lists of regulators match.
