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

-Example:
-pmic@0 {
- compatible = "sprd,sc2731";
- reg = <0>;
- spi-max-frequency = <26000000>;
- interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
- interrupt-controller;
- #interrupt-cells = <2>;
- #address-cells = <1>;
- #size-cells = <0>;
