Subject: [PATCH v2 5/5] cpufreq: qcom-hw: Add cpufreq support for SM8250 SoC
Date: Tue, 15 Sep 2020 12:54:23 +0530 [thread overview]
Message-ID: <20200915072423.18437-6-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20200915072423.18437-1-manivannan.sadhasivam@linaro.org>
SM8250 SoC uses EPSS block for carrying out the cpufreq duties. Hence, add
support for it in the driver with relevant dev data.
