Subject: [PATCH 05/10] dt-bindings: clock: sunxi: Export CLK_DRAM for devfreq
Date: Tue, 28 Sep 2021 23:42:49 -0500 [thread overview]
Message-ID: <20210929044254.38301-6-samuel@sholland.org> (raw)
In-Reply-To: <20210929044254.38301-1-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.
