Subject: [PATCH v2 1/6] dt-bindings: clock: sunxi: Export CLK_DRAM for devfreq
Date:   Sun,  3 Oct 2021 20:27:34 -0500

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.
