Since we don't implement full features of PSCI on our platform, that
is why we wants to know whether there is registration of platform
suspend method.
BTW, from the git log, it seems psci.c doesn't register system suspend
until Linux 4.4.
if so, before 4.4, how aarch64 support such as str, echo mem >
/sys/power/state , suspend flow?
appreciate your kind explanation.
