[PATCH v10 25/27] arm64: kernel: Respect the hierarchical CPU topology in DT for PSCI

From: Ulf Hansson
Date: Thu Nov 29 2018 - 12:48:01 EST


To let the PSCI driver parse for the hierarchical CPU topology in DT and
thus potentially initiate the corresponding PM domain data structures,
let's call psci_dt_topology_init() from the existing topology_init()
subsys_initcall.
