/**
* 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.
*/
/**
* enum iwl_plat_pm_mode - platform power management mode
*
* @IWL_D0I3_MODE_OFF - d0i3 is disabled
* @IWL_D0I3_MODE_ON_IDLE - enter d0i3 when device is idle
* (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
* behavior when in idle mode (i.e. runtime power management) or when
* in system-wide suspend (i.e WoWLAN).
*
* @IWL_PLAT_PM_MODE_DISABLED: power management is disabled for this
* device. At runtime, this means that nothing happens and the
* device always remains in active. In system-wide suspend mode,
* it means that the all connections will be closed automatically
* by mac80211 before the platform is suspended.
* @IWL_PLAT_PM_MODE_D3: the device goes into D3 mode (i.e. WoWLAN).
* For runtime power management, this mode is not officially
* supported.
* @IWL_PLAT_PM_MODE_D0I3: the device goes into D0I3 mode.
