From f4d7ad156ad2253d5ec3e79ea36309e27b8fabc7 Mon Sep 17 00:00:00 2001
From: Jerome Brunet <jbrunet@baylibre.com>
Date: Thu, 30 Mar 2017 15:19:04 +0200
Subject: [PATCH] ARM64: dts: meson-gx: add audio controller nodes
Add audio controller nodes for Amlogic meson gxbb and gxl.
This includes the audio-core node, the i2s and spdif DAIs, i2s and spdif
aiu DMAs.
Audio on this SoC family is still a work in progress. More nodes are likely
to be added later on (pcm DAIs, input DMAs, etc ...)
