[PATCH v2 2/4] arm64: dts: mediatek: mt8186: Wire up CPU frequency/voltage scaling

From: Chen-Yu Tsai
Date: Fri Jun 09 2023 - 03:30:17 EST


This adds clocks, dynamic power coefficients, and OPP tables for the CPU
cores, so that everything required at the SoC level for CPU freqency and
voltage scaling is available.
