Although the XPS 9360 and XPS 9365 are currently the only Dell products on
the market that do the wakeup this way, this is part of Dell's BIOS and EC
codebase.  As other Dell products start to ship Windows 10 with Modern Standby
and (eventually) Linux with Suspend-to-Idle I'd expect this list to be growing.

I know that we talked about this previously in relation to the EC notification
of going in to suspend-to-idle and you had instead marked it across all Dell Inc systems.

Rather than hardcode a whitelist of platform that can do this, could you do the
same thing here and allow EC wakeups across Dell Inc. systems?

Thanks,
