Date: Sun, 20 Dec 2020 16:29:05 -0800 From: Danny Lin <danny@...ag0n.dev> To: unlisted-recipients:; (no To-header on input) Cc: Danny Lin <danny@...ag0n.dev>, Andy Gross <agross@...nel.org>, Bjorn Andersson <bjorn.andersson@...aro.org>, Rob Herring <robh+dt@...nel.org>, linux-arm-msm@...r.kernel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 1/3] arm64: dts: qcom: sm8150: Define CPU topology sm8150 has a big.LITTLE CPU setup with DynamIQ, so all cores are within the same CPU cluster and LLC (Last-Level Cache) domain. Define this topology to help the scheduler make decisions.
