From e7c54567cac3bd96acd726f4421385ec25cac85d Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Tue, 2 Mar 2021 15:09:59 +0300 Subject: [PATCH] ARM: tegra: nexus7: Specify all CPU cores as cooling devices If CPU0 is unplugged the cooling device can not rebind to CPU1. And if CPU0 is plugged in again, the cooling device may fail to initialize. If the CPUs are mapped with the physical CPU0 to Linux numbering CPU1, the cooling device mapping will fail. Hence specify all CPU cores as a cooling devices in the device-tree.
