[PATCH 1/3] Documentation/gpu: limit main toctree depth to 2

[Jani Nikula]

The main GPU documentation toctree has no limit to the toctree depth,
which means the main GPU index page recursively includes all the
headings in all of GPU documentation in the single table of
contents. This makes getting any kind of overview of the documentation
really difficult.

Limit the main toctree depth to 2 i.e. show at most two levels of
headings.

[PATCH 2/3] Documentation/gpu: add some tables of contents to large documents

[Jani Nikula]

Some of the GPU documentation pages are quite long, with various levels
of details. Add document internal tables of contents to the larger
documents to make them easier to navigate.

The index.rst in the sub-directories have toctrees, which provide
similar overviews.

Fix one missing newline at the end of drm-uapi.rst while at it,
primarily because rst should have it, and secondarily because my editor
rst mode refuses to save the file without it.

[PATCH 3/3] Documentation/gpu/rfc: fix toctree

[Jani Nikula]

Just one toctree is enough. The .rst suffixes are superfluous in the
toctree. Fix indent. Add missing newline at the end of the file.
