927  * Pure dynamic property declaration. A pure dynamic property is a property
928  * for which a driver's prop_op(9E) implementation will return a value on
929  * demand, but the property name does not exist on a property list (global,
930  * driver, system, or hardware) - the person asking for the value must know
931  * the name and type information.
932  *
933  * For a pure dynamic property to show up in a di_init() devinfo shapshot, the
934  * devinfo driver must know name and type. The i_ddi_prop_dyn_t mechanism
935  * allows a driver to define an array of the name/type information of its
936  * dynamic properties. When a driver declares its dynamic properties in a
937  * i_ddi_prop_dyn_t array, and registers that array using
938  * i_ddi_prop_dyn_driver_set() the devinfo driver has sufficient information
939  * to represent the properties in a snapshot - calling the driver's
940  * prop_op(9E) to obtain values.
941  *
942  * The last element of a i_ddi_prop_dyn_t is detected via a NULL dp_name value.
943  *
944  * A pure dynamic property name associated with a minor_node/dev_t should be
945  * defined with a dp_spec_type of S_IFCHR or S_IFBLK, as appropriate.  The
946  * driver's prop_op(9E) entry point will be called for all
947  * ddi_create_minor_node(9F) nodes of the specified spec_type. For a driver
948  * where not all minor_node/dev_t combinations support the same named
949  * properties, it is the responsibility of the prop_op(9E) implementation to
950  * sort out what combinations are appropriate.
951  *
952  * A pure dynamic property of a devinfo node should be defined with a
953  * dp_spec_type of 0.
954  *
955  * NB: Public DDI property interfaces no longer support pure dynamic
956  * properties, but they are still still used.  A prime example is the cmlb
957  * implementation of size(9P) properties. Using pure dynamic properties
958  * reduces the space required to maintain per-partition information. Since
959  * there are no public interfaces to create pure dynamic properties,
960  * the i_ddi_prop_dyn_t mechanism should remain private.
