| 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>; |
| }; |
