[PATCH 2/3] arm64: dts: exynos: gs101: align reboot and poweroff writes with downstream

From: André Draszik
Date: Thu Feb 06 2025 - 08:08:46 EST


For power off, downstream only clears bit 8 and leaves all other bits
untouched, whereas this here ends up setting bit 8 and clearing all
others, due to how sysconf-poweroff parses the DT.

For reboot, downstream writes 0x00000002 whereas this here ends up
setting bit 1 only and leaving all others untouched.

I noticed this discrepancy while debugging some reboot related
differences between up- and downstream and it's useful to align the
behaviour here.
