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 Signed-off-by: Urja Rannikko <urjaman@gmail.com> Reviewed-by: Patrick Delaunay <patrick.delaunay@st.com> (Update comment to help understand the patch) Signed-off-by: Kever Yang <kever.yang@rock-chips.com>
