From 458ad21df1c38d229aaa4c494199168d742302ab Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 21 Jun 2016 11:20:24 +0100 Subject: ARM: EXYNOS: Fixups for big-endian operation If the kernel is built big endian, then using the __raw read and write IO accessors is not going to work as they end up writing big-endian data to little-endian IO registers. Fix this by using the readl and writel relaxed versions which ensure little endian IO.
