drm/vkms: Add kerneldoc entry

drm: extract drm_atomic_uapi.c

2018-09-09T12:19:18Z

This leaves all the commit/check and state handling in drm_atomic.c, while pulling all the uapi glue and the huge ioctl itself into a seprate file. This seems to almost perfectly split the rather big drm_atomic.c file into 2 equal sizes. Also adjust the kerneldoc and type a very terse overview text. v2: Rebase. v3: Fix tiny typo. v4: - Fixup armada, newly converted atomic driver hooray! - Fixup msm/dpu1, newly added too.

drm: Update todo.rst

2018-09-09T12:19:18Z

- drmP.h is now fully split up. - vkms is happening (and will gain its own todo and docs under a new vkms.rst file real soon) - legacy cruft is completely hidden now, drm_vblank.c is split out from drm_irq.c now. I've decided to drop the task to split out drm_legacy.ko, partially because Dave already rejected a patch to hide the old dri1 drivers better. Current state feels good enough to me. - best_encoder atomic cleanup is done (it's now the default, not even exported anymore) - bunch of smaller things v2: - Explain why the drm_legacy.ko task is dropped (Emil). - typos (Sam). v3: Fix typo (Ilia) Reviewed-by: Emil Velikov Reviewed-by: Heiko Stuebner Cc: Ilia Mirkin Cc: Sam Ravnborg Cc: Emil Velikov Signed-off-by: Daniel Vetter Cc: Gustavo Padovan Cc: Maarten Lankhorst Cc: Sean Paul Cc: David Airlie Link: https://patchwork.freedesktop.org/patch/msgid/20180905181509.19530-1-daniel.vetter@ffwll.ch

drm/atomic: trim driver interface/docs

2018-09-09T12:19:18Z

Remove the kerneldoc and EXPORT_SYMBOL which aren't used and really shouldn't ever be used by drivers directly. Unfortunately this means we need to move the set_writeback_fb function around to avoid a forward decl.

drm/fourcc: Add DOC: overview comment

2018-08-21T17:02:30Z

There's a number of things which haven't previously been documented around the usage of format modifiers. Capture the current understanding in an overview comment and add it to the rst documentation. Ideally, the generated documentation would also include documentation of all of the #defines, but the kernel-doc system doesn't currently support kernel-doc comments on #define constants.
