Subject: [PATCH 5.4 110/453] arm64: dts: exynos: Include common syscon restart/poweroff for Exynos7

From: Paweł Chmiel <pawel.mikolaj.chmiel@...il.com>

[ Upstream commit 73bc7510ea0dafb4ff1ae6808759627a8ec51f5a ]

Exynos7 uses the same syscon reboot and poweroff nodes as other Exynos
SoCs, so instead of duplicating code we can just include common dtsi
file, which already contains definitions of them. After this change,
poweroff node will be also available, previously this dts file did
contain only reboot node.

Fixes: fb026cb65247 ("arm64: dts: Add reboot node for exynos7")
Fixes: b9024cbc937d ("arm64: dts: Add initial device tree support for exynos7")
