 /**
- * enum iwl_d0i3_mode - d0i3 mode
+ * DOC: Platform power management
+ *
+ * There are two types of platform power management: system-wide
+ * (WoWLAN) and runtime.
+ *
+ * In system-wide power management the entire platform goes into a low
+ * power state (e.g. idle or suspend to RAM) at the same time and the
+ * device is configured as a wakeup source for the entire platform.
+ * This is usually triggered by userspace activity (e.g. the user
+ * presses the suspend button or a power management daemon decides to
+ * put the platform in low power mode).  The device's behavior in this
+ * mode is dictated by the wake-on-WLAN configuration.
+ *
+ * In runtime power management, only the devices which are themselves
+ * idle enter a low power state.  This is done at runtime, which means
+ * that the entire system is still running normally.  This mode is
+ * usually triggered automatically by the device driver and requires
+ * the ability to enter and exit the low power modes in a very short
+ * time, so there is not much impact in usability.
+ *
+ * The terms used for the device's behavior are as follows:
+ *
+ *	- D0: the device is fully powered and the host is awake;
+ *	- D3: the device is in low power mode and only reacts to
+ *		specific events (e.g. magic-packet received or scan
+ *		results found);
+ *	- D0I3: the device is in low power mode and reacts to any
+ *		activity (e.g. RX);
+ *
+ * These terms reflect the power modes in the firmware and are not to
+ * be confused with the physical device power state.  The NIC can be
+ * in D0I3 mode even if, for instance, the PCI device is in D3 state.
+ */

- *	(e.g. no active references)
- * @IWL_D0I3_MODE_ON_SUSPEND - enter d0i3 only on suspend
- *	(in case of 'any' trigger)
+ * This enumeration describes the device's platform power management

+ * in system-wide suspend (i.e WoWLAN).
+ *
+ * @IWL_PLAT_PM_MODE_DISABLED: power management is disabled for this
