   576	 * dtpm_create_hierarchy - Create the dtpm hierarchy
   577	 * @hierarchy: An array of struct dtpm_node describing the hierarchy
   578	 *
   579	 * The function is called by the platform specific code with the
   580	 * description of the different node in the hierarchy. It creates the
   581	 * tree in the sysfs filesystem under the powercap dtpm entry.
   582	 *
   583	 * The expected tree has the format:
   584	 *
   585	 * struct dtpm_node hierarchy[] = {
   586	 *	[0] { .name = "topmost", type =  DTPM_NODE_VIRTUAL },
   587	 *	[1] { .name = "package", .type = DTPM_NODE_VIRTUAL, .parent = &hierarchy[0] },
   588	 *	[2] { .name = "/cpus/cpu0", .type = DTPM_NODE_DT, .parent = &hierarchy[1] },
   589	 *	[3] { .name = "/cpus/cpu1", .type = DTPM_NODE_DT, .parent = &hierarchy[1] },

   592	 *	[6] { }
   593	 * };
   594	 *
   595	 * The last element is always an empty one and marks the end of the
   596	 * array.
   597	 *
   598	 * Return: zero on success, a negative value in case of error. Errors
   599	 * are reported back from the underlying functions.
