Subject: [PATCH] arm64: dts: qcom: sm8750: Add capacity and DPC properties
Date: Fri, 26 Dec 2025 18:02:58 +0530 [thread overview]
Message-ID: <20251226123258.1444419-1-ankit.sharma@oss.qualcomm.com> (raw)
The "capacity-dmips-mhz" and "dynamic-power-coefficient" are
used to build Energy Model which in turn is used by EAS to take
placement decisions.
