drm/atomic: Unconfuse the old_state mess in commmit_tail

2016-11-22T10:11:57+00:00

I totally butcherd the job on typing the kernel-doc for these, and no
one realized. Noticed by Russell. Maarten has a more complete approach
to this confusion, by making it more explicit what the new/old state
is, instead of this magic switching behaviour.

v2:
- Liviu pointed out that wait_for_fences is even more magic. Leave
that as @state, and document @pre_swap better.
- While at it, patch in header for the reference section.
- Fix spelling issues Russell noticed.

v3: Fix up the @pre_swap note (Liviu): Also s/synchronous/blocking/,
since async flip is something else than non-blocking.

drm: document standard connector properties

2016-11-18T08:45:07+00:00

There's a really big pile of additional connector properties, a lot of
them standardized. But they're all for specific outputs (panels, TV,
scaling, ...) so I left them out for now since this is enough for a
start.

I typed this to give Manasi a place to add her new link status
property documentation.

v2: forgot to git add all the bits (Manasi).

v3: Be more epxlicit about integrated tiled panels (Archit)

drm: Move tile group code into drm_connector.c

2016-11-15T14:30:38+00:00

And also put the overview section into the KMS Properties part of the
docs, instead of randomly-placed within the helpers - this is part of
the uabi.

With this patch I think drm_crtc.[hc] is cleaned up and entirely
documented.

drm: Extract drm_mode_config.[hc]

2016-11-15T14:23:29+00:00

And shuffle the kernel-doc structure a bit since drm_crtc.[hc] now
only contains CRTC-related functions and structures.

v2:
- rebase onto drm-misc
- don't forget to move drm_mode_config_cleanup.
- move 2 internal decls under the right heading (Chris)

drm/print: Move kerneldoc next to definition

2016-11-15T11:55:24+00:00

kerneldoc expects the comment next to definitions, otherwise it can't
pick up exported vs. internal stuff.

This fixes a warning from the doc build done with:

not sure why it failed to spot this.
