	or not for the drivers to prepare for cluster collapse.

	- qcom,hyp-psci: This property is used to determine if the cpu

        enters the low power mode within hypervisor.

	- qcom,reset-level: This property is used to determine in this

	low power mode only control logic power collapse happens or memory

	logic power collapse aswell happens or retention state.

	The accepted values for this property are:

		"LPM_RESET_LVL_NONE" - No power collapse

		"LPM_RESET_LVL_RET"  - Retention state

		"LPM_RESET_LVL_GDHS" - Only control logic power collapse (GDHS)

		"LPM_RESET_LVL_PC" - Control logic and memory logic

					power collapse (PC)
