    Subject[PATCH v10 4/9] devicetree: bindings: Document first ROHM BD70528 bindings
    Document bindings for regulators (3 bucks, 3 LDOs and 2 LED
    drivers) and 4 GPIO pins which can be configured for I/O or
    as interrupt sources withe configurable trigger levels.

    +* ROHM BD70528 Power Management Integrated Circuit bindings
    +
    +BD70528MWV is an ultra-low quiescet current general purpose single-chip
    +power management IC for battery-powered portable devices. The IC
    +integrates 3 ultra-low current consumption buck converters, 3 LDOs and 2
    +LED Drivers. Also included are 4 GPIOs, a real-time clock (RTC), a 32kHz
    +clock gate, high-accuracy VREF for use with an external ADC, flexible
    +dual-input power path, 10 bit SAR ADC for battery temperature monitor and
    +1S battery charger with scalable charge currents.
    +
    +Required properties:
    + - compatible : Should be "rohm,bd70528"
    + - reg : I2C slave address.
    + - interrupts : The interrupt line the device is connected to.
    + - interrupt-controller : To indicate BD70528 acts as an interrupt controller.
    + - #interrupt-cells : Should be 2. Usage is compliant to the 2 cells
    + variant of ../interrupt-controller/interrupts.txt
    + - gpio-controller : To indicate BD70528 acts as a GPIO controller.
    + - #gpio-cells : Should be 2. The first cell is the pin number and
    + the second cell is used to specify flags. See
    + ../gpio/gpio.txt for more information.
    + - #clock-cells : Should be 0.
    + - regulators: : List of child nodes that specify the regulators.
    + Please see ../regulator/rohm,bd70528-regulator.txt
    +
    +Optional properties:
    + - clock-output-names : Should contain name for output clock.
    +
    +Example:
    +/* external oscillator */
    +osc: oscillator {
    + compatible = "fixed-clock";
    + #clock-cells = <1>;
    + clock-frequency = <32768>;
    + clock-output-names = "osc";
    +};
    +
    +pmic: pmic@4b {
    + compatible = "rohm,bd70528";
    + reg = <0x4b>;
    + interrupt-parent = <&gpio1>;
    + interrupts = <29 GPIO_ACTIVE_LOW>;
    + clocks = <&osc 0>;
    + #clock-cells = <0>;
    + clock-output-names = "bd70528-32k-out";
    + #gpio-cells = <2>;
    + gpio-controller;
    + interrupt-controller;
    + #interrupt-cells = <2>;
