Subject: [PATCH 01/43] iwlwifi: mvm: add CT-KILL notification
Date: Wed,  2 Mar 2016 09:56:02 +0200	[thread overview]
Message-ID: <1456905404-14435-1-git-send-email-emmanuel.grumbach@intel.com> (raw)
In-Reply-To: <0BA3FCBA62E2DC44AF3030971E174FB32EA50146@hasmsx107.ger.corp.intel.com>

From: Chaya Rachel Ivgi <chaya.rachel.ivgi@intel.com>

Up to today the driver was notified of the temperature from the FW
and decided whether to enter CT-kill or not.
>From now on, the FW will decide when to enter CT-kill and will notify
the driver.
Add support for this notification.
