Subject: sysreset: switch to using SYSRESET_POWER_OFF for poweroff
X-Git-Tag: v2019.10-rc3~10^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=857f39d7b09804566b23e0f20fcb04601f2ecb52;p=platform%2Fkernel%2Fu-boot.git

sysreset: switch to using SYSRESET_POWER_OFF for poweroff

It seems that SYSRESET_POWER_OFF was added recently, and all previous code
used SYSRESET_POWER for poweroff. SYSRESET_POWER is supposed to be a
PMIC-level power cycle, not a poweroff.

(Comment by Simon Glass)
SYSRESET_POWER means to do a power reset (removing and reinstating all power)
SYSRESET_POWER_OFF means to turn the device off and leave it off
