14description: |
15 Spreadtrum PMICs belonging to the SC27xx series integrate all mobile handset
16 power management, audio codec, battery management and user interface support
17 functions in a single chip. They have 6 major functional blocks:
18 - DCDCs to support CPU, memory
19 - LDOs to support both internal and external requirements
20 - Battery management system, such as charger, fuel gauge
21 - Audio codec
22 - User interface functions, such as indicator, flash LED and so on
23 - IC level interface, such as power on/off control, RTC, typec and so on
