From 93b8e6fda11757a20df21f3fc18e12789841f173 Mon Sep 17 00:00:00 2001 From: Parth Pancholi Date: Fri, 10 Jun 2016 19:19:55 +0100 Subject: [PATCH] ARM: dts: sd_600eval: Fix eMMC lockup issue This board locks up if we stress test the eMMC, as the regulator s4 is unable to supply enough current for all the peripherials attached to it. As this supply is wired up to most of the peripherials including DDR, it resulted in such lockup. This patch fixes this issue by setting s4 regulator correctly with Auto power mode.
