Subject: [PATCH v3 1/3] arm64: dts: uniphier: add sound node for UniPhier
Date:   Tue, 13 Feb 2018 22:01:54 +0900
Message-Id: <20180213130156.27827-2-suzuki.katsuhiro@socionext.com>
In-Reply-To: <20180213130156.27827-1-suzuki.katsuhiro@socionext.com>
References: <20180213130156.27827-1-suzuki.katsuhiro@socionext.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patch adds audio controller, codec and simple card node of
UniPhier AIO sound system for LD11/20 SoCs.

Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com>

---

Changes in v3:
  - Move sound and spdif-out nodes to root from soc node
  - Use phandle of endpoint directly instead of port node
  - Describe connections between AIO and EVEA in *.dtsi
    because these cores are in inside of SoC
