Subject: [PATCH 2/2] arm64: dts: exynos: Remove unneeded DSI and DECON address/size cells in Exynos5433
Date:   Mon, 18 Jun 2018 19:42:16 +0200
Message-Id: <20180618174216.24801-2-krzk@kernel.org>
In-Reply-To: <20180618174216.24801-1-krzk@kernel.org>
References: <20180618174216.24801-1-krzk@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The decon, decon_tv and dsi nodes have only one child port so
address/size mappings are not necessary.  This fixes DTC warnings like:

    Warning (graph_child_address): /soc/decon@13800000/ports:
        graph node has single child node 'port@0', #address-cells/#size-cells are not necessary
