    1 Spreadtrum SC27xx Power Management Integrated Circuit (PMIC)
    2 
    3 The Spreadtrum SC27xx series PMICs contain SC2720, SC2721, SC2723, SC2730
    4 and SC2731. The Spreadtrum PMIC belonging to SC27xx series integrates all
    5 mobile handset power management, audio codec, battery management and user
    6 interface support function in a single chip. It has 6 major functional
    7 blocks:
    8 - DCDCs to support CPU, memory.
    9 - LDOs to support both internal and external requirement.
   10 - Battery management system, such as charger, fuel gauge.
   11 - Audio codec.
   12 - User interface function, such as indicator, flash LED and so on.
   13 - IC level interface, such as power on/off control, RTC and typec and so on.
   14 
   15 Required properties:
   16 - compatible: Should be one of the following:
   17         "sprd,sc2720"
   18         "sprd,sc2721"
   19         "sprd,sc2723"
   20         "sprd,sc2730"
   21         "sprd,sc2731"
   22 - reg: The address of the device chip select, should be 0.
   23 - spi-max-frequency: Typically set to 26000000.
   24 - interrupts: The interrupt line the device is connected to.
   25 - interrupt-controller: Marks the device node as an interrupt controller.
   26 - #interrupt-cells: The number of cells to describe an PMIC IRQ, must be 2.
   27 - #address-cells: Child device offset number of cells, must be 1.
   28 - #size-cells: Child device size number of cells, must be 0.

   30 Example:
   31 pmic@0 {
   32         compatible = "sprd,sc2731";
   33         reg = <0>;
   34         spi-max-frequency = <26000000>;
   35         interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
   36         interrupt-controller;
   37         #interrupt-cells = <2>;
   38         #address-cells = <1>;
   39         #size-cells = <0>;
   40 };
