Subject: [PATCH 2/2] ARM: dts: imx51-babbage: Pass a real clock to the codec
Date: Sun,  9 Jun 2013 22:07:47 -0300	[thread overview]
Message-ID: <1370826467-30399-2-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1370826467-30399-1-git-send-email-festevam@gmail.com>

From: Fabio Estevam <fabio.estevam@freescale.com>

On imx51_babbage the codec clock is activated via GPIO4_26.

Provide a real clock to the sgtl5000 codec via device tree.
