Subject: [PATCH 1/4] clk/soc: mediatek: mt8183: Bind clock driver from platform device
Date:   Mon, 18 May 2020 13:31:53 +0200
Message-Id: <20200518113156.25009-1-matthias.bgg@kernel.org>

From: Matthias Brugger <matthias.bgg@gmail.com>

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.
