Subject: [PATCH] ARM: dts: imx6: RIoTboard explicitly define pad settings

From: [email-masked] (Iain Paton)
Date: Sun, 13 Jul 2014 16:56:35 +0100

Instead of relying on defaults or bootloader settings, explicitly define
all pad settings.

This resolves reported issues of no analogue audio output.

I don't know if it's possible at this point, but it would be good if this 
could make it into 3.16.
