Is that tested ? I see only cpu_{on,off} available on this platform with
PSCI v0.1. Did you add cpu_suspend, idle-states and then gave it a spin ?
Or do you have some other idle driver with which this is tested ?

Also I don't understand how "always-on" is linked to hrtimer. Always on
timers are just selected to be broadcast timer without sacrificing(simply
keeping) a cpu to be always active for broadcast purposes.
