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.

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>;
