From efdbd7345f8836f7495f3ac6ee237d86cb3bb6b0 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Mon, 21 Sep 2015 10:51:09 -0500 Subject: dt-bindings: consolidate display related bindings This is a quite large renaming to consolidate display related bindings into a single "display" directory from various scattered locations of video, drm, gpu, fb, mipi, and panel. The prior location was somewhat based on the Linux driver location, but bindings should be independent of that.
