Subject: ath9k: Add a module parameter to invert LED polarity.
Date: Mon, 11 Apr 2016 04:48:54 +0200 [thread overview]
Message-ID: <mailman.4.1465068303.3969.ath9k-devel@lists.ath9k.org> (raw)
From: Vittorio Gambaletta (VittGam) <linux-wireless@vittgam.net>
commit cd84042ce9040ad038e958bc67a46fcfc015c736 upstream.
The LED can be active high instead of active low on some hardware.
Add the led_active_high module parameter. It defaults to -1 to obey
platform data as before.
Setting the parameter to 1 or 0 will force the LED respectively
active high or active low.
