Subject: [PATCH 09/12] wl12xx: add dynamic_ps_timeout debugfs file
Date: Mon, 30 Jan 2012 14:00:54 +0200 [thread overview]
Message-ID: <1327924857-1250-10-git-send-email-eliad@wizery.com> (raw)
In-Reply-To: <1327924857-1250-1-git-send-email-eliad@wizery.com>
From: Eyal Shapira <eyal@wizery.com>
Enable read/write of dynamic_ps_timeout which controls the timeout
of the dynamic PS implemented in the FW.
dynamic_ps_timeout is the timeout (in msec) until going back to PS
when there's no Rx/Tx
