[PATCH 3/4] clk/soc: mediatek: mt6779: Bind clock driver from platform device

From: matthias . bgg
Date: Mon May 18 2020 - 07:32:13 EST


From: Matthias Brugger <matthias.bgg@xxxxxxxxx>

The mmsys driver is now the top level entry point for the multimedia
system (mmsys), we bind the clock driver by creating a platform device.
We also bind the MediaTek DRM driver which is not yet implement and
therefor will errror out for now.
