From 93032e31a5f12df847639db3ad0b7f300bf44b7b Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Fri, 14 Oct 2016 10:17:32 +0100 Subject: [PATCH] MIPS: Malta: Fixup reboot Commit 10b6ea0959de ("MIPS: Malta: Use syscon-reboot driver to reboot") converted the Malta board to use the generic syscon-reboot driver to handle reboots, but incorrectly used the value 0x4d rather than 0x42 as the magic to write to the reboot register. I also incorrectly believed that syscon/regmap would default to native endianness, but this isn't the case. Force this by specifying with a native-endian property in the devicetree.
