Subject: [PATCH v2 4/4] k3dma: delete axi_config
Date:   Fri,  6 Jul 2018 11:55:21 +0800
Message-Id: <20180706035521.13736-5-guodong.xu@linaro.org>
In-Reply-To: <20180706035521.13736-1-guodong.xu@linaro.org>
References: <20180706035521.13736-1-guodong.xu@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Li Yu <liyu65@hisilicon.com>

Axi_config controls whether DMA resources can be accessed in non-secure
mode, such as linux kernel. The setting is actually done in
bootloader stage.

This patch removes axi_config from k3dma driver.
