Subject: [PATCH 3/5] ath9k_hw: Fix thermal issue with UB94
Date: Tue, 4 Jan 2011 13:17:05 +0530 [thread overview]
Message-ID: <19746.53369.901444.615660@gargle.gargle.HOWL> (raw)
From: Sujith Manoharan <Sujith.Manoharan@atheros.com>
Hardcode the output voltage of x-PA bias LDO to the lowest
value for UB94. The card doesn't get too hot now.
