889  * Pure dynamic property declaration. A pure dynamic property is a property
890  * for which a driver's prop_op(9E) implementation will return a value on
891  * demand, but the property name does not exist on a property list (global,
892  * driver, system, or hardware) - the person asking for the value must know
893  * the name and type information.
894  *
895  * For a pure dynamic property to show up in a di_init() devinfo shapshot, the
896  * devinfo driver must know name and type. The i_ddi_prop_dyn_t mechanism
897  * allows a driver to define an array of the name/type information of its
898  * dynamic properties. When a driver declares its dynamic properties in a
899  * i_ddi_prop_dyn_t array, and registers that array using
900  * i_ddi_prop_dyn_driver_set() the devinfo driver has sufficient information
901  * to represent the properties in a snapshot - calling the driver's
902  * prop_op(9E) to obtain values.
903  *
904  * The last element of a i_ddi_prop_dyn_t is detected via a NULL dp_name value.
905  *
906  * A pure dynamic property name associated with a minor_node/dev_t should be
907  * defined with a dp_spec_type of S_IFCHR or S_IFBLK, as appropriate.  The
908  * driver's prop_op(9E) entry point will be called for all
909  * ddi_create_minor_node(9F) nodes of the specified spec_type. For a driver
910  * where not all minor_node/dev_t combinations support the same named
911  * properties, it is the responsibility of the prop_op(9E) implementation to
912  * sort out what combinations are appropriate.
913  *
914  * A pure dynamic property of a devinfo node should be defined with a
915  * dp_spec_type of 0.
916  *
917  * NB: Public DDI property interfaces no longer support pure dynamic
918  * properties, but they are still still used.  A prime example is the cmlb
919  * implementation of size(9P) properties. Using pure dynamic properties
920  * reduces the space required to maintain per-partition information. Since
921  * there are no public interfaces to create pure dynamic properties,
922  * the i_ddi_prop_dyn_t mechanism should remain private.
