From 719ed1f8a1f93b2c9d855392a69493da107ae703 Mon Sep 17 00:00:00 2001
From: Phil Elwell <phil@raspberrypi.org>

Subject: [PATCH] BCM270X_DT: Add reference to audio_pins to CM dtb
The CM1 dtb contains an empty audio_pins node, but no reference to it.
Adding the usual pinctrl reference from the audio node enables the
audremap overlay (and others) to easily turn on audio.
