Subject: [PATCH v4 01/11] dt-bindings: sdhci-omap: Add properties for using external dma
Date: Mon, 6 Jan 2020 16:31:23 +0530 [thread overview]
Message-ID: <20200106110133.13791-2-faiz_abbas@ti.com> (raw)
In-Reply-To: <20200106110133.13791-1-faiz_abbas@ti.com>
From: Chunyan Zhang <zhang.chunyan@linaro.org>
sdhci-omap can support both external dma controller via dmaengine
framework as well as ADMA which standard SD host controller
provides. Add binding documentation for these external dma properties.
