Subject: [PATCH v4 1/4] ASoC: codecs: adau1701: move firmware download to adau1701_reset()
Date: Mon, 24 Jun 2013 16:31:29 +0200 [thread overview]
Message-ID: <1372084292-4859-2-git-send-email-zonque@gmail.com> (raw)
In-Reply-To: <1372084292-4859-1-git-send-email-zonque@gmail.com>
The chip needs a new download after each reset, so the code to do that
needs to live in adau1701_reset().
