From e6ed3f533d54a92f8d67d301f9209ca64d593e03 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Tue, 9 Aug 2016 14:19:04 +0200 Subject: [PATCH] ARM: dts: alt: add MMCIF support Define the Alt board dependent part of the MMCIF device node. Like the Silk the board has eMMC chip along with the necessary voltage regulator (note that the Vcc/Vccq regulator is dummy -- it's required by the MMCIF driver but doesn't actually exist on the board). Based on work for the Silk board by Vladimir Barinov and Sergei Shtylyov.
