There is a word missing in the above sentence between "System Controller" and "can't be", and I believe the word is "that".

So, add support for this property and enable
PME switch output if this property is present.

A property that "enables" something means that you are using Device Tree as a way to encode some sort of policy, maybe this is just the wording here and what you would want to say is that describing the node with a 'wakeup-source' property indicates that the device is wake-up capable, regardless of the presence/absence of an interrupt parent?
