From e379c6a137bba5c40d9a126b71a667b4d7f5697a Mon Sep 17 00:00:00 2001 From: Daniel Stone Date: Tue, 4 Apr 2017 21:38:56 +0100 Subject: [PATCH] Headers: Sync drm{,_mode}.h with the kernel Generated using make headers_install, based on drm-misc-next commit 5db06a8a98f515f67446a69c57577c4c363ec65d. This clarifies the comments around modifiers such that they are per-framebuffer rather than per-plane, adds the beginnings of aspect ratio mode flags, link status properties, and updates the 'reserved' field from vblank events to include the CRTC ID. v2: Split into separate patch, pull in full kernel changes. v3: Undo revert of connector-type enums, since it is not actually harmful.
