    Subject[PATCH v2 07/17] dt_bindings: mfd: Add ROHM BD71815 PMIC
    Document DT bindings for ROHM BD71815.

    BD71815 is a single-chip power management IC mainly for battery-powered
    portable devices. The IC integrates 5 bucks, 7 LDOs, a boost driver for
    LED, a battery charger with a Coulomb counter, a real-time clock, a 32kHz
    clock and two general-purpose outputs although only one is documented by
    the data-sheet.

    Changes since v1:
    - fixed patch ordering to meet ref dependencies
    - added missing blank lines
    - clkout-mode changed from string to tristated (uint)
    - added default for rsense resistor

    + BD71815AGW is a single-chip power management ICs for battery-powered
    + portable devices. It integrates 5 buck converters, 8 LDOs, a boost driver
    + for LED and a 500 mA single-cell linear charger. Also included is a Coulomb
    + counter, a real-time clock (RTC), and a 32.768 kHz clock gate and two GPOs.

    + Usage of BD71828 GPIO pins can be changed via OTP. This property can be

    + rohm,enable-hidden-gpo:
    + description: |
    + The BD71815 has undocumented GPO at pin E5. Pin is marked as GND at the
    + data-sheet as it's location in the middle of GND pins makes it hard to
    + use on PCB. If your board has managed to use this pin you can enable the
    + second GPO by defining this property. Dont enable this if you are unsure
    + about how the E5 pin is connected on your board.
