Subject: [PATCH] arm64: dts: sdm845: Add CPU topology
Date: Mon, 14 Jan 2019 10:42:55 -0800 [thread overview]
Message-ID: <20190114184255.258318-1-mka@chromium.org> (raw)
The 8 CPU cores of the SDM845 are organized in two clusters of 4 big
("gold") and 4 little ("silver") cores. Add a cpu-map node to the DT
that describes this topology.
