From 5e949f0c79917f3fd8512a3b66b0c861e03ec5a6 Mon Sep 17 00:00:00 2001 From: Marcin Wojtas Date: Fri, 14 Nov 2014 16:57:29 +0100 Subject: [PATCH] ARM: mvebu: enable no-1-8-v flag for Armada 385 DB SDHCI interface The Marvell Armada 38x SoC's SDHCI interface is capable of using 1.8v voltage, needed for driving "UHS-I" SD cards at their full speed. It is not, however, possible on the DB board. Due to physical connectivity connector supply is tied to 3v and any attempt of changing voltage in order to operate in the fastest UHS modes fails. This patch enables equivalent SDHCI quirk in order to adjust controller operation to system capabilities.
