Subject: [PATCH v2 03/12] arm64: dts: qcom: sm6115: Add cpufreq-hw support
Date: Wed, 30 Nov 2022 21:09:41 +0100	[thread overview]
Message-ID: <20221130200950.144618-4-a39.skl@gmail.com> (raw)
In-Reply-To: <20221130200950.144618-1-a39.skl@gmail.com>

Add cpufreq-hw node and assign qcom,freq-domain properties
to CPUs to enable CPU clock scaling.
