We are using Hikey boards as a reference for ARM64 development. I have looked for documentation regarding "Power Management" in Linux kernel, however my searches were not very successful.
I have tried to do the following:
$ echo mem > /sys/power/state
[ 2234.871713] PM: suspend entry 2016-02-11 17:05:03.872904787 UTC
[ 2234.878654] PM: Syncing filesystems ... done.
[ 2234.900361] Freezing user space processes ... (elapsed 0.001 seconds) done.
[ 2234.901713] Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
[ 2234.901724] Suspending console(s) (use no_console_suspend to debug)
However I did not know how to add the peripherals to the "wakeup" domain.
Can someone educate me on the power-management for Hikey? Thanks
