Subject: [PATCH v10 27/27] arm64: dts: hikey: Convert to the hierarchical CPU topology layout
Date: Thu, 29 Nov 2018 18:47:00 +0100 [thread overview]
Message-ID: <20181129174700.16585-28-ulf.hansson@linaro.org> (raw)
In-Reply-To: <20181129174700.16585-1-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.
Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
