10 Typically each idle state has the following associated properties:
12 - name: The name of the idle state as defined by the firmware.
14 - flags: indicating some aspects of this idle states such as the
15 extent of state-loss, whether timebase is stopped on this
16 idle states and so on. The flag bits are as follows:

3 ARM provides idle-state node to define the cpuidle states, as defined in [1].
4 cpuidle-qcom is the cpuidle driver for Qualcomm SoCs and uses these idle
5 states. Idle states have different enter/exit latency and residency values.
6 The idle states supported by the QCOM SoC are defined as -
16 trigger to execute the SPM state machine. The SPM state machine waits for the
18 hierarchy to enter standby states, when all cpus are idle. An interrupt brings
19 the SPM state machine out of its wait, the next step is to ensure that the
