Subject: [PATCH 6/8] ASoC: Do a warm reset after cold when resetting the WM9713
Date: Thu, 30 Oct 2008 15:58:27 +0000 [thread overview]
Message-ID: <1225382309-1827-6-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1225382309-1827-5-git-send-email-broonie@opensource.wolfsonmicro.com>
The WM9713 comes out of cold reset in low power mode so always requires
a warm reset to bring up the AC97 link after a cold reset.
