From 8f4ed8fc51569307d6aec959e1f1c1c790c7fcd7 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Fri, 9 Jun 2023 15:29:03 +0800 Subject: [PATCH] arm64: dts: mediatek: mt8186: Wire up CPU frequency/voltage scaling 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.
