When probing platform drivers let's check if corresponding devices have
"wakeup-source" property defined (either in device tree, ACPI, or static
platform properties) and automatically enable such devices as wakeup
sources for the system. This will help us standardize on the name for this
property and reduce amount of boilerplate code in the drivers.
ACPI has other ways of telling the OS that the device is wakeup-capable,
but I guess the property in question can be used too (as long as it is
consistent with the other methods).
Just curious to know what you mean when you say this property can also
be used with ACPI. Do you mean we could use "wakeup-source" DSD ?
If so, won't that go against rule for DSD (i.e we *should not* bypass the
existing mechanisms defined by the ACPI, e.g. _SxW in this case)
What if the device doesn't use ACPI PM and still can wake up the system?
