Subject: [PATCH v1 7/7] arm64: dts: sdm845: wireup the thermal trip points to cpufreq
Since the big and little cpus are in the same frequency domain, use all
of them for mitigation in the cooling-map. At the lower trip points we
restrict ourselves to throttling only a few OPPs. At higher trip
temperatures, allow ourselves to be throttled to any extent.
