Subject: [PATCH v10 25/27] arm64: kernel: Respect the hierarchical CPU topology in DT for PSCI
Date:   Thu, 29 Nov 2018 18:46:58 +0100
Message-Id: <20181129174700.16585-26-ulf.hansson@linaro.org>
In-Reply-To: <20181129174700.16585-1-ulf.hansson@linaro.org>
References: <20181129174700.16585-1-ulf.hansson@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
