Subject: [PATCH v2 3/8] dt-bindings: sdhci-omap: Add properties for using external dma
Date: Sat, 16 Feb 2019 00:50:28 +0530	[thread overview]
Message-ID: <20190215192033.24203-4-faiz_abbas@ti.com> (raw)
In-Reply-To: <20190215192033.24203-1-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.
