[PATCH v4 1/1] arm64: dts: sdm845: wireup the thermal trip points to cpufreq
From: Amit Kucheria
Date: Wed Feb 06 2019 - 05:35:41 EST
Since all cpus in the big and little clusters, respectively, are in the
same frequency domain, use all of them for mitigation in the
cooling-map. We end up with two cooling devices - one each for the big
and little clusters.
