That was the plan, yes. The TZ1090 SoC can do suspend to RAM, but not in
mainline yet, so there are a few loose ends still.

I'll have a look at what we can do to sort it out. I have a work in
progress patchset somewhere to add the suspend support to mainline, then
at least the code could be enabled.

Thanks for pointing it out.

Cheers
James
