1Overview 2######## 3 4The interfaces and APIs provided by the power management subsystem 5are designed to be architecture and SOC independent. This enables power 6management implementations to be easily adapted to different SOCs and 7architectures. 8 9The architecture and SOC independence is achieved by separating the core PM 10infrastructure from implementations of the SOC specific components. 11Thus a coherent abstraction is presented to the rest of the OS and the application layer. 12 13The power management features are classified into the following categories. 14 15* System Power Management 16* Device Power Management 17
