Subject: [PATCH v3 2/7] dt-bindings: opp: accept array of frequencies
Date: Fri, 13 May 2022 08:13:42 +0200 [thread overview]
Message-ID: <20220513061347.46480-3-krzysztof.kozlowski@linaro.org> (raw)
In-Reply-To: <20220513061347.46480-1-krzysztof.kozlowski@linaro.org>
Devices might need to control several clocks when scaling the frequency
and voltage. Allow passing array of clock frequencies, similarly to the
voltages.
