+From f134380c19eb38bc276d6d86fa575821c3493c60 Mon Sep 17 00:00:00 2001
+From: Matthias Reichl <hias@horus.com>
+Date: Sun, 22 Jan 2017 12:49:36 +0100
+Subject: [PATCH] BCM270x DT: Consolidate audio card overlays
+
+Reference 3.3V / 5V system rails instead of instantiating local
+regulators.
+
+Add missing power supply properties for codecs where these are
+required according to the DT bindings docs.
