Subject: [PATCH v3 1/2] ARM: dts: exynos: Move syscon poweroff and restart nodes under the PMU
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>
---
Previously was "Fix missing missing reg warning for syscon restart
nodes" to 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
but this warnings are gone in v4.17-rc1 since 9130ba884640
("scripts/dtc: Update to upstream version v1.4.6-9-gaadd0b65c987")
