Subject: [PATCH 3.5 4/4] ath9k_hw: apply internal regulator settings on AR933x
Date: Thu, 24 May 2012 14:32:22 +0200 [thread overview]
Message-ID: <1337862742-10574-4-git-send-email-nbd@openwrt.org> (raw)
In-Reply-To: <1337862742-10574-3-git-send-email-nbd@openwrt.org>
On AR933x, the internal regulator settings need to be applied before the
PLL init to avoid stability issues.
