From: Laurent Pinchart Date: Fri, 10 Mar 2017 10:18:12 +0000 (+0530) Subject: drm: bridge: dw-hdmi: Move the driver to a separate directory. X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=35dc8aabc8783d6322a59d774af2858e5955d2ab;p=openwrt%2Fstaging%2Fblogic.git 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).
