Class properties make QOM introspection simpler and easier, as it
doesn't require an object to be instantiated.  This series
converts a few existing object_property_add*() calls to register
class properties instead.

Hello Eduardo,

IIUC, most of the properties can be dev-spec or class-spec.
Do we have any principle or rule to specify the property to be dev or class?

Maybe if the property which is always the same between instances can
be a class-property?

Thanks,
Li Qiang

If you are talking about having the same value, this is not the
use case for class properties.  Registering a class property just
means all instances of the object will have that property (but
each instance can have the property set to a different value),
and makes this information available for introspection before
instantiating the object.
