From fc7a3d9e9cd01e2679076c655f2bc4b04efbfa01 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Wed, 29 Apr 2020 12:36:42 +0200 Subject: thermal: cpuidle: Register cpuidle cooling device The cpuidle driver can be used as a cooling device by injecting idle cycles. When the property is set, register the cpuidle driver with the idle state node pointer as a cooling device. The thermal framework will do the association automatically with the thermal zone via the cooling-device defined in the device tree cooling-maps section.
