Subject: [PATCH 3/3] arm64: dts: register Hi6220's thermal zone for power allocator
Date: Sat, 20 Feb 2016 23:52:09 +0800 [thread overview]
Message-ID: <1455983529-9559-4-git-send-email-leo.yan@linaro.org> (raw)
In-Reply-To: <1455983529-9559-1-git-send-email-leo.yan-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>
With profiling Hi6220's power modeling so get dynamic coefficient and
sustainable power. So pass these parameters from DT.
Now enable power allocator wit only one actor for CPU part, so directly
use cluster0's thermal sensor for monitoring temperature.
