Subject: [PATCH 10/10] DT: QCOM: Add thermal mitigation to msm8996
Date: Tue, 12 Dec 2017 14:31:37 +0200 [thread overview]
Message-ID: <1513081897-31612-11-git-send-email-ilialin@codeaurora.org> (raw)
In-Reply-To: <1513081897-31612-1-git-send-email-ilialin@codeaurora.org>
Add thermal mitigation configuration to msm8996.
With the cpufreq-dt OPP table the CPU frequency may be
scaled and therefore throttled by the thermal config.
