I think that removal of this stuff will effectively remove the
restart/poweroff handlers from:
1. Other defconfigs, like multi_v7
2. Custom configs.
This will also break old DTBs that don't have a "syscon-poweroff" device
node that contains the necessary PMU regmap, offset and mask information.
Previously this code was always compiled in for ARCH_EXYNOS. Now it is
not so I am thinking about selecting necessary drivers from main exynos
Kconfig symbol. That could be tricky though, because "select" should be
used only for non-visible symbols.
Any ideas how to solve that?
Is true that select should only be used for non-visible symbols but there
are others user visible symbols that are selected by ARCH_EXYNOS such as
EXYNOS_THERMAL. So I think selecting the regmap syscon reset stuff there
is a sensible option.
Yes, another example is MFD_SYSYCON which is selected from Kconfig.
Also CONFIG_POWER_RESET_SYSCON is enable in arch/arm64/config/defconfig.
So both approaches are taken here.
will go with maintainer suggestion here.

Krzysztof
