From 30154ed8a43d82f5746af3fe2ec7a74c649ca27a Mon Sep 17 00:00:00 2001 From: Konstantin Porotchkin Date: Tue, 23 May 2017 16:11:40 +0300 Subject: [PATCH] arm64: dts: marvell: Enable second SDHCI controller in Armada 37xx The Armada 37xx SoCs has 2 SDHCI interfaces. This patch adds the second one. Moreover, the Armada 37xx DB v2 board populates the 2 SDHCI interfaces. The second interface is using pluggable module that can either have an SD connector or eMMC on it. This patch adds support for SD module in the device DT.
