From 17170ec17109bdcd26bf542392a5bafcb6a5732f Mon Sep 17 00:00:00 2001 From: Amit Kucheria Date: Tue, 29 Jan 2019 10:25:13 +0530 Subject: [PATCH] cpufreq: qoriq: Use auto-registration of thermal cooling device Use the CPUFREQ_IS_COOLING_DEV flag to allow cpufreq core to automatically register as a thermal cooling device. This allows removal of boiler plate code from the driver. Signed-off-by: Amit Kucheria Acked-by: Viresh Kumar Reviewed-by: Daniel Lezcano Signed-off-by: Rafael J.
