13 The purpose of the simple MMC power sequence provider is to supports a set
14 of common properties between various SOC designs. It thus enables us to use

13 HiSilicon 6421v600 should be connected inside a MIPI System Power Management
14 (SPMI) bus. It provides interrupts and power supply.

14 1 - Introduction
17 ARM systems contain HW capable of managing power consumption dynamically,
18 where cores can be put in different low-power states (ranging from simple wfi
19 to power gating) according to OS PM policies. The CPU states representing the
20 range of dynamic idle states that a processor can enter at run-time, can be
