Subject: [PATCH v3 1/6] dt-bindings: clock: sunxi: Export CLK_DRAM for devfreq
Date: Wed, 17 Nov 2021 21:18:36 -0600 [thread overview]
Message-ID: <20211118031841.42315-2-samuel@sholland.org> (raw)
In-Reply-To: <20211118031841.42315-1-samuel@sholland.org>
The MBUS node needs to reference the CLK_DRAM clock, as the MBUS
hardware implements memory dynamic frequency scaling using this clock.
Export this clock for SoCs which will be getting a devfreq driver.
Acked-by: Rob Herring <robh@kernel.org>
