From 6b55297581eaf4f1850b4d25b29dd55a239272cc Mon Sep 17 00:00:00 2001 From: Ikjoon Jang Date: Tue, 25 Feb 2020 16:07:53 +0800 Subject: [PATCH] arm64: dts: mt8183: adjust cpuidle target residency Split a cluster level cpuidle state into two, so mt8183 variant boards can adjust parameters for each cluster, and reduce cluster0's default target residency to 1000us as power measurements showed that its minimum residency is slightly less than cluster1's 1300us.
