Subject: [PATCH 4/4] MIPS: Ingenic: Initial YSH & ATIL CU Neo board support.
Date:   Fri, 22 Nov 2019 21:11:29 +0800
Message-Id: <1574428289-21764-5-git-send-email-zhouyanjie@zoho.com>
In-Reply-To: <1574428289-21764-1-git-send-email-zhouyanjie@zoho.com>
References: <1574428289-21764-1-git-send-email-zhouyanjie@zoho.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add a device tree for the Ingenic X1000 based YSH & ATIL CU Neo board.
Note that this is unselectable via Kconfig until the X1000 SoC is made
selectable in a later commit.
