Subject: [resend PATCH v6 01/12] dt-bindings: display: mediatek: Add mmsys binding description

From: Matthias Brugger <[email protected]>

The MediaTek DRM has a block called mmsys, which sets
the routing and enalbes the different blocks.
This patch adds one line for the mmsys bindings description.

This patch conflicts with 5.5-rc, please resend this patch base on
5.5-rc1.

The original binding document for mmsys is in [1], I think we should not
define it in duplicate. Maybe you could remove the original document.

I think we should keep it, as it describes some requirements that are otherwise
lost. I'll adapt the mmsys description and add a hint to it, like we do for dsi
and dpi.
