Subject: [PATCH 2/5] arm64: dts: renesas: r8a7796: Add multi-cluster definition
Date: Tue, 27 Feb 2018 11:19:52 +0900 [thread overview]
Message-ID: <1519697995-6061-3-git-send-email-gaku.inami.xh@renesas.com> (raw)
In-Reply-To: <1519697995-6061-1-git-send-email-gaku.inami.xh@renesas.com>
This patch adds the "cpu-map" for multi-cluster into r8a7796
device-tree. This definition is used to parse the cpu topology.
