    Subject[RFC PATCH v2 1/6] dt-bindings: mfd: add entry for Marvell 88PM886 PMIC
    Date
    From: Karel Balej <balejk@matfyz.cz>

    Marvell 88PM886 is a PMIC with several subdevices such as onkey,
    regulators or battery and charger. It comes in at least two revisions,
    A0 and A1 -- only A1 is described here at the moment.

    Notes:
    RFC v2:
    - Address Rob's feedback:
    - Drop mention of 88PM880.
    - Make sure the file passes bindings check (add the necessary header
    and fix `interrupt-cells`).
    - Other small changes.
    - Add regulators. Changes with respect to the regulator RFC series:
    - Address Krzysztof's comments:
    - Drop unused compatible.
    - Fix sub-node pattern.
