13 It would be much simpler for the platform to describe its power domain tree
16 #. The generic PSCI code generates MPIDRs in order to populate the power domain
20 levels in the power domain tree to four.
23 mechanism used to populate the power domain topology tree.
25 #. The current arrangement of the power domain tree requires a binary search
27 domain node. During a power management operation, the tree is traversed from
36 #. The attributes of a core power domain differ from the attributes of power
37 domains at higher levels. For example, only a core power domain can be identified
39 performing a power management operation on the core power domain.
50 Describing a power domain tree
59 where the power domain tree does not have a single root node, for example,
62 #. Each subsequent entry corresponds to a power domain and contains the number
73 The following example power domain topology tree will be used to describe the
126 power domain. MPIDRs could be allocated in any manner and will not be used to
141 for a core domain will be the same as the index returned by
165 domain tree descriptor will not describe any core power domains which are
170 in the power domain descriptor, that is, the number of core nodes described
179 to represent leaf and non-leaf power domain nodes in the tree.
184 * The following two data structures implement the power domain tree. The tree
185 * is used to track the state of all the nodes i.e. power domain instances
188 * CPU power domain i.e. non-leaf nodes.
192 * Index of the first CPU power domain node level 0 which has this node
198 * Number of CPU power domains which are siblings of the domain indexed
204 /* Index of the parent power domain node */
213 /* Index of the parent power domain node */
219 The power domain tree is implemented as a combination of the following data

241 For the example power domain tree illustrated above, the ``psci_cpu_pd_nodes``
300 domain nodes do not need to be identified.
