I could not see hikey960 entering into suspend state. How did you see the system can enter into suspend state?
when I enter "cat /sys/power/state", nothings could be shown.
Also, there is no effect when entering "echo mem>/sys/power/state" or "echo standby>/sys/power/state" or "echo freeze>/sys/power/state".
When I traced this kernel, no one call "suspend_set_ops" to init the pm_states.
How could I enter suspend and resume operations on HiKey960?
