With Sphinx 1.5.3 I get the warning:

	WARNING: primary_domain 'C' not found, ignored.

It seems that domain names in Sphinx are case-sensitive and for the C
domain the name must be lower case.

The format of the structure references in device_link.rst is
incorrect, because it doesn't cause proper references to the
struct data types to be generated (for struct dev_pm_domain in
particular).

Fix that by using the :c:type:`struct name <name>` convention
for encoding references to struct data types.

There is a better way to represent structure references than it was
done in device.rst by commit 730c4c05 (PM / sleep / docs: Convert
PM notifiers document to reST), which is to use "struct name" as a
link caption (e.g. :c:type:`struct device <device>`).  That will
cause sphinx to generate a proper reference to the data type in
question (struct device in the example above) and "struct name"
will work as the link in the HTML output.

Fix device.rst by using that convention where applicable.

Use PYTHONDONTWRITEBYTECODE=1 to prevent python from creating .pyc files
in the source tree. Python 3.2 has a __pycache__ scheme [1], but before
that the only alternative seems to be to copy the source files to the
build tree to ensure the .pyc files are created there too. Just prevent
.pyc file generation for simplicity.

Considering the small amount of python code to compile (assuming sphinx
itself has .pyc around), the impact on build is neglible.

Convert deviceiobook.tmpl to RST and incorporate it into the driver API
manual.

Like the rest of our documentation, this one could use some work.  There's
no mention of ioremap() and friends, no mention of io_read*() and friends.
But we have nice documentation for all those folks writing new drivers that
do port I/O :).

The :c:func: notation has been left off of all the read*/write* functions.
There's no kerneldoc comments for them anyway, so those links will never be
live, and writing a bunch of repetitive "read a byte from I/O memory"
comments lacks appeal.

$type_struct_full and friends are only used by the restructuredText
backend, because it needs to separate enum/struct/typedef/union from
the name of the type.  However, $type_struct is *also* used by the rST
backend.  This is confusing.

This patch replaces $type_struct's use in the rST backend with a new
$type_fallback; it modifies $type_struct so that it can be used in the
rST backend; and creates regular expressions like $type_struct
for enum/typedef/union, for use in all backends.

Note that, compared to $type_*_full, in the new regexes $1 includes both
the "kind" and the name (before, $1 was pretty much a constant).
