Subject: [PATCH 18/18] arm64: dts: hikey: Convert to the hierarchical CPU topology layout
Date: Mon, 13 May 2019 21:23:00 +0200
Message-ID: <20190513192300.653-19-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20190513192300.653-1-ulf.hansson@linaro.org>

To enable the OS to manage last-man standing activities for a CPU, while an
idle state for a group of CPUs is selected, let's convert the Hikey
platform into using the hierarchical CPU topology layout.
