Subject: [PATCH 2/3] ARM: dts: exynos: Fix missing missing reg warning for syscon restart nodes
Fix DTC warnings like:
arch/arm/boot/dts/exynos4412-trats2.dtb: Warning (simple_bus_reg):
Node /soc/syscon-poweroff missing or empty reg/ranges property
arch/arm/boot/dts/exynos4412-trats2.dtb: Warning (simple_bus_reg):
Node /soc/syscon-reboot missing or empty reg/ranges property
by moving the syscon poweroff and restart nodes into the PMU (Power
Management Unit) node. The PMU node is the actual block responsible for
power management, including typical Exynos on/off/restart procedures.
Therefore the syscon poweroff and restart nodes logically belong to it.
Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>
---
Tested on Exynos5420 and Exynos4412. Other tests are welcomed.
