From 7b920aae917da3486f0084fd1b77b2f59f521309 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 23 Aug 2016 14:56:12 +0200 Subject: [PATCH] dt-bindings: mxsfb: Add new bindings for the MXSFB driver Add new DT bindings for new MXSFB driver that is using the OF graph to parse the video output structure instead of hard-coding the display properties into the MXSFB node. The old MXSFB fbdev driver bindings are preserved in the same file in the "Old bindings" section.
