UAPI Changes: - Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI (Robert) Cross-subsystem Changes: - Standardize sync_file.txt documentation format (Mauro) Core Changes: - Turf drm_[cm]alloc functions for kvmalloc alternatives (Michal) - Add optional mode_valid() hook to crtc/encoder/bridge (Jose) - Improve documentation around mode validation/alteration (Daniel) - Reduce sync_file construction time by deferring name creation (Chris) Driver Changes: - pl111: Wire up the clock divider and add debugfs (Eric) - various: Fix include notation and remove -Iinclude/drm (Masahiro) - stm: Add Benjamin Gaignard and Vincent Abriou as STM maintainers (Vincent) - various: Miscellaneous trivial fixes to pl111/stm/vgem/vc4 Cc: Michal Hocko <mhocko@suse.com> Cc: Eric Anholt <eric@anholt.net> Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Robert Foss <robert.foss@collabora.com> Cc: Vincent Abriou <vincent.abriou@st.com> Cc: Jose Abreu <Jose.Abreu@synopsys.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mauro Carvalho Chehab <mchehab@s-opensource.com> * tag 'drm-misc-next-2017-05-26' of git://anongit.freedesktop.org/git/drm-misc: (55 commits) dma-buf/sync-file: Defer creation of sync_file->name sync_file.txt: standardize document format gpu: drm: gma500: remove two more dead variable drm/doc: Clarify mode_fixup vs. atomic_check a bit more drm/doc: Document adjusted/request modes a bit better drm: Add crtc/encoder/bridge->mode_valid() callbacks MAINTAINERS: update drm/stm maintainers list drm/stm: ltdc: fix duplicated arguments drm/pl111: Fix return value check in pl111_amba_probe() drm/amd: include <linux/delay.h> instead of "linux/delay.h" drm: Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ to UAPI drm/vgem: Fix return value check in vgem_init() drm/blend: Fix comment typ-o drm/stm: remove unneeded -Iinclude/drm compiler flag drm/vc4: fix include notation and remove -Iinclude/drm flag drm/pl111: Add a debugfs node to dump our registers. drm/pl111: make structure mode_config_funcs static drm/pl111: make structure pl111_display_funcs static drm/pl111: Register the clock divider and use it. drm: drop drm_[cm]alloc* helpers ...
