39b73fb15e iwlwifi: Thermal Throttling Management - Part 1
Part 1 of Thermal Throttling Management -

Thermal Throttling feature is used to put NIC into low power state when
driver detect the Radio temperature reach pre-defined threshold

Two Thermal Throttling Management Methods; this patch introduce the
Legacy Thermal Management:
   IWL_TI_0: normal temperature, system power state
   IWL_TI_1: high temperature detect, low power state
   IWL_TI_2: higher temperature detected, lower power state
   IWL_TI_CT_KILL: critical temperature detected, lowest power state

Once get into CT_KILL state, uCode go into sleep, driver will stop all
the active queues, then move to IWL_TI_CT_KILL state; also set up 5
seconds timer to toggle CSR flag, uCode wake up upon CSR flag change,
then measure the temperature.
If temperature is above CT_KILL exit threshold, uCode go backto sleep;
if temperature is below CT_KILL exit threshold, uCode send Card State
Notification response with appropriate CT_KILL status flag, and uCode
remain awake, Driver receive Card State Notification Response and update
the card temperature to the CT_KILL exit threshold.

7af2c46078 iwlwifi: clean up PS code
This removes all the dead code that tries to adjust the power
saving level based on the system AC state (inacceptable policy
in the kernel) or based on overtemp conditions (unused).

Also, pass _all_ policy wrt. enabling PS to mac80211, since
we do not use the power_disabled internally I now use that to
mirror the mac80211 CONF_PS setting. When mac80211 turns off
CONF_PS we follow suit. This means that the user power level
(which can currently only be set from sysfs) is not touched
for mac80211 powersave changes.

This means no "association status" checks are necessary since
mac80211 will not allow power save to be enabled when not
associated.

d25aabb0a1 iwlwifi: unify iwlagn and 3945 power save management
This patch unifies 3945 and iwlagn power save management
This patch also better separates system state from user setting.
System state shall be removed later as this shall be shifted to user space

1125eff3ae iwl3945: Remove power related definitions from 3945 code
Most of the power (not TX power, but power management) structures and
definitions are duplicated accross iwl-power.h and iwl-3945.h. We should try
to only use the iwl header.

04816448d8 iwlwifi: use the results from disconnected antenna algorithm
This patch makes usage of the results from disconnected antenna alg to
know how many antennas are connected.

It also synchronizes between the chain noise alg and the W/A that
disables power management during association. All the antennas must be
enables during the chain noise algorithm. Hence, power management is
restored only after the completion of the algorithm.

In the future, we will need to update the AP that we don't support MIMO
if there is only one antenna connected. We also need to update the rate
scaling algorithm.

c90a74bae1 iwlwifi: allow association on radar channel in power save
This patch disables power save upon association and enables it back
after association. This allows to associate to AP on a radar channel
if power save is enabled.

Radar and passive channels are not allowed for TX (required for association)
unless RX is received but PS may close the radio and no RX will be received
effectively failing association.
