H A Dqcom,idle-state.txt3 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 -
31 state. Retention may have a slightly higher latency than Standby.
44 code in the EL for the SoC. On SoCs with write-back L1 cache, the cache has to
50 be flushed, system bus, clocks - lowered, and SoC main XO clock gated and
