[PATCH 4/4] drm/doc: Convert to markdown

Danilo Cesar Lemes de Paula danilo.cesar at collabora.co.uk
Thu Jul 23 11:16:27 PDT 2015


DRM Docbook is now Markdown ready. This means its doc is able to
use markdown text on it.

* Documentation/DocBook/drm.tmpl: Contains a table duplicated from
  drivers/gpu/drm/i915/i915_reg.h. This is not needed anymore

* drivers/gpu/drm/drm_modeset_lock.c: had a code example that used
  to look pretty bad on html. Fixed by using proper code markup.

* drivers/gpu/drm/drm_prime.c: Remove spaces between lines to make
  a proper markup list.

* drivers/gpu/drm/i915/i915_reg.h: Altought pandoc supports tables,
  it doesn't support table cell spanning. But we can use fixed-width
  for those special cases.

* include/drm/drm_vma_manager.h: Another code example that should be
  proper indented with four spaces.
