From d88a2db7f7ef0a231ef5fc7b91b01f6400ce4d27 Mon Sep 17 00:00:00 2001

Subject: [PATCH 234/286] drm: bridge: dw-hdmi: Move the driver to a separate
directory.
The driver is already made of 5 separate source files. Move it to a
newly created directory named synopsys where more Synopsys bridge
drivers can be added later (for the DisplayPort controller for
instance).
