Subject: [PATCH v2 21/22] arm64: dts: ls104x: make dma-coherent global to the SoC
Date:   Wed, 26 Sep 2018 16:22:46 +0300
Message-Id: <20180926132247.10971-22-laurentiu.tudor@nxp.com>
In-Reply-To: <20180926132247.10971-1-laurentiu.tudor@nxp.com>
References: <20180926132247.10971-1-laurentiu.tudor@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Laurentiu Tudor <laurentiu.tudor@nxp.com>

These SoCs are really completely dma coherent in their entirety so add
the dma-coherent property at the soc level in the device tree and drop
the instances where it's specifically added to a few select devices.
