Subject: [PATCH] dt-bindings: sdhci-omap: Add properties for using external dma
Date: Tue, 22 Jan 2019 16:47:06 +0800 [thread overview]
Message-ID: <20190122084706.11522-1-zhang.chunyan@linaro.org> (raw)
In-Reply-To: <20190121232057.GA30919@bogus>
sdhci-omap can support both external dma controller via dmaengine
framework as well as ADMA which standard SD host controller
provides.
