drm: Extract drm_vblank.[hc]

2017-06-01T06:02:14+00:00

drm_irq.c contains both the irq helper library (optional) and the
vblank support (optional, but part of the modeset uapi, and doesn't
require the use of the irq helpers at all.

Split this up for more clarity of the scope of the individual bits.

v2: Move misplaced hunks to this patch (Stefan).

drm/doc: atomic overview, with graph

2017-03-14T14:13:37+00:00

I want to split up a few more things and document some details better
(like how exactly to subclass drm_atomic_state). And maybe also split
up the helpers a bit per-topic, but this should be a ok-ish start for
better atomic overview.

v2: Spelling and clarifications (Eric).

v3: Implement suggestion from Gabriel to fix the graph.

v4: Review from Laurent.

drm/doc: Consistent kerneldoc include order

2017-03-14T14:13:20+00:00

First overview text (if there is any), then headers (since generally
you want to start out with the data structures), then all the other
stuff with functions.

Most of this is pre-shpinx, since with the old docbook only the
overview stuff was pulled in directly. Everything else was put in a
per-section index, so include order didn't really matter.

drm: Update kerneldoc for drm_crtc.[hc]

2017-01-25T15:36:23+00:00

After going through all the trouble of splitting out parts from
drm_crtc.[hc] and then properly documenting each I've entirely
forgotten to show the same TLC for CRTCs themselves!

Let's make amends asap.

v2: Review from Eric.

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).

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.
