Mauro Carvalho Chehab a700767a76 docs: requirements.txt: recommend Sphinx 1.7.9
As discussed at the linux-doc ML, while we'll still support
version 1.3, it is time to recommend a more modern version.

So, let's switch the minimal requirements to Sphinx 1.7.9,
as it has the "-jauto" flag, with makes a lot faster when
building documentation.

Joris Gutjahr 1bb37a3567 doc-guide:kernel-doc.rst: Reference to foobar
In the Function documentation Section of kernel-doc.rst
there is a function_name() function as an example for
how to make a comment about a function.

But at the end of that example there is a reference to foobar
instead of function_name.

I think that should rather be function_name, because that
was the placeholder the whole example was using.

Mike Rapoport f2e8603604 Documentation/sphinx: allow "functions" with no parameters
When kernel-doc:: specified in .rst document without explicit directives,
it outputs both comment and DOC: sections. If a DOC: section was explicitly
included in the same document it will be duplicated. For example, the
output generated for Documentation/core-api/idr.rst [1] has "IDA
description" in the "IDA usage" section and in the middle of the API
reference.

This patch enables using "functions" directive without parameters to output
all the documentation excluding DOC: sections.

Mauro Carvalho Chehab 3259081991 MAINTAINERS & files: Canonize the e-mails I use at files

As such, let's remove the entries that point to the old

For the files written with a copyright with mchehab@s-opensource,
let's keep Samsung on their names, using mchehab+samsung@kernel.org,
in order to keep pointing to my employer, with sponsors the work.

For the files written before I join Samsung (on July, 4 2013),
let's just use mchehab@kernel.org.

For bug reports, we can simply point to just kernel.org, as
this will reach my mchehab+samsung inbox anyway.

Matthew Wilcox 46347502b0 Restructure kernel-doc.rst
I found the layout confusing with multiple introductions to what
kernel-doc is and how to use it.

I made the following changes:
 - Moved the 'Including kernel-doc comments' section to the end of
   the document -- we should explain what it *is* before we explain
   how to integrate it.
 - Moved the 'Recommendations' subsection to the top.  We want people
   to know what to document before telling them how to do it.
 - Rewrite the 'Writing kernel-doc comments' section, integrating
   the 'Recommendations' subsection and a paragraph from 'How to format
   kernel-doc comments'.
 - Remove the paragraph about the kernel-doc script; we're supposed to
   be teaching people how to use punctuation to write pretty documentation,
   not documenting the build tooling.
 - Split the 'Parameters and member arguments' section into 'Function
   parameters' and 'Members'.  Structure members are not commonly
   referred to as arguments.
 - Integrate the 'private:' and 'public:' tag descriptions into the
   'Members' section.
 - Move the 'In-line member documentation comments' subsection up to be
   with the 'Members' section.

Mauro Carvalho Chehab 8ad7216316 scripts: kernel-doc: parse next structs/unions
There are several places within the Kernel tree with nested
structs/unions, like this one:

  struct ingenic_cgu_clk_info {
    const char *name;
    enum {
      CGU_CLK_NONE = 0,
      CGU_CLK_EXT = BIT(0),
      CGU_CLK_PLL = BIT(1),
      CGU_CLK_GATE = BIT(2),
      CGU_CLK_MUX = BIT(3),
      CGU_CLK_MUX_GLITCHFREE = BIT(4),
      CGU_CLK_DIV = BIT(5),
      CGU_CLK_FIXDIV = BIT(6),
      CGU_CLK_CUSTOM = BIT(7),
    } type;
    int parents[4];
    union {
      struct ingenic_cgu_pll_info pll;
      struct {
        struct ingenic_cgu_gate_info gate;
        struct ingenic_cgu_mux_info mux;
        struct ingenic_cgu_div_info div;
        struct ingenic_cgu_fixdiv_info fixdiv;
      };
      struct ingenic_cgu_custom_info custom;
    };
  };

Currently, such struct is documented as:

	**Definition**

	::
	struct ingenic_cgu_clk_info {
	    const char * name;
	};

	**Members**

	``name``
	  name of the clock

With is obvioulsy wrong. It also generates an error:
	drivers/clk/ingenic/cgu.h:169: warning: No description found for parameter 'enum'

However, there's nothing wrong with this kernel-doc markup: everything
is documented there.

It makes sense to document all fields there. So, add a
way for the core to parse those structs.

With this patch, all documented fields will properly generate
documentation.

Markus Heiser db6ccf23e8 docs-rst: automatically convert Graphviz and SVG images
This patch brings scalable figure, image handling and a concept to
embed *render* markups:

* DOT (http://www.graphviz.org)
* SVG

For image handling use the 'image' replacement::

    .. kernel-image::  svg_image.svg
       :alt:    simple SVG image

For figure handling use the 'figure' replacement::

    .. kernel-figure::  svg_image.svg
       :alt:    simple SVG image

       SVG image example

Embed *render* markups (or languages) like Graphviz's **DOT** is
provided by the *render* directive.::

  .. kernel-render:: DOT
     :alt: foobar digraph
     :caption: Embedded **DOT** (Graphviz) code.

     digraph foo {
      "bar" -> "baz";
     }

The *render* directive is a concept to integrate *render* markups and
languages, yet supported markups:

* DOT: render embedded Graphviz's **DOT**
* SVG: render embedded Scalable Vector Graphics (**SVG**)

So, simplify the script's internal documntation to a bare minimum,

This way, a quick help is still available at the command line,
while the complete one is maintained at the ReST format.
