Subject: [PATCH 2/8 v3] Documentation: bindings: k3dma: Add binding for hisi-dma-avail-chan
Date:   Thu, 10 Jan 2019 09:34:06 -0800
Message-Id: <1547141652-8660-3-git-send-email-john.stultz@linaro.org>
In-Reply-To: <1547141652-8660-1-git-send-email-john.stultz@linaro.org>
References: <1547141652-8660-1-git-send-email-john.stultz@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Some dma channels can be reserved for secure mode or other
hardware on the SoC, so provide a binding for a bitmask
listing the available channels for the kernel to use.
