^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) Description:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) 		The /sys/devices/.../power_state attribute is only present for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		device objects representing ACPI device nodes that provide power
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		management methods.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		If present, it contains a string representing the current ACPI
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		power state of the given device node.  Its possible values,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		"D0", "D1", "D2", "D3hot", and "D3cold", reflect the power state
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 		names defined by the ACPI specification (ACPI 4 and above).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		If the device node uses shared ACPI power resources, this state
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		determines a list of power resources required not to be turned
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 		off.  However, some power resources needed by the device node in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 		higher-power (lower-number) states may also be ON because of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 		some other devices using them at the moment.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		This attribute is read-only.
