[PATCH v3 1/6] dt-bindings: clock: sunxi: Export CLK_DRAM for devfreq

From: Samuel Holland
Date: Wed Nov 17 2021 - 22:18:50 EST


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.
