Now that Limits h/w is enabled to monitor thermal events around cpus and throttle the cpu frequencies, remove cpufreq cooling device for the CPU thermal zones which does software throttling of cpu frequencies. Signed-off-by: Thara Gopinath <thara.gopinath@linaro.org> --- v2->v3: - Improved the subject header and descrption to better reflect the patch as per Matthias's review comments. v1->v2: Removing only cooling maps for cpu specific thermal zones keeping the trip point definitions intact as per Daniel's suggestion. This is to ensure that thermal zone temparature and trip violation information is available to any userspace daemon monitoring these zones. arch/arm64/boot/dts/qcom/sdm845.dtsi | 136 --------------------------- 1 file changed, 136 deletions(-)
