    Subject[PATCH 3/3] ARM: dts: sun7i: lamobo-r1: Add backup battery charging property
    Date
    This adds the axp20x backup property to the lamobo-r1 device-tree,
    that allows charging the backup battery attached to its AXP209.

    It is especially useful since the battery is used for the RTC module.
