Subject: [PATCH v4 34/41] docs: kdoc_files: document KernelFiles() ABI

The KernelFiles is the main entry point to run kernel-doc,
being used by both tools/docs/kernel-doc and
Documentation/sphinx/kerneldoc.py.

It is also used on QEMU, which also uses the kernel-doc
libraries from tools/lib/python/kdoc.

Properly describe its ABI contract.

     Parse kernel-doc tags on multiple kernel source files.
 
-    There are two type of parsers defined here:
+    This is the main entry point to run kernel-doc. This class is initialized
+    using a series of optional arguments:
+
+    ``verbose``
+        If True, enables kernel-doc verbosity. Default: False.
+
+    ``out_style``
+        Class to be used to format output. If None (default),
+        only report errors.
+
+    ``xforms``
+        Transforms to be applied to C prototypes and data structs.
+        If not specified, defaults to xforms = CFunction()
+
+    ``werror``
+        If True, treat warnings as errors, retuning an error code on warnings.
+
+        Default: False.
+
+    ``wreturn``
+        If True, warns about the lack of a return markup on functions.
+
+        Default: False.
+    ``wshort_desc``
+        If True, warns if initial short description is missing.
+
+        Default: False.
+
+    ``wcontents_before_sections``
+        If True, warn if there are contents before sections (deprecated).
+        This option is kept just for backward-compatibility, but it does
+        nothing, neither here nor at the original Perl script.
+
+        Default: False.
+
+    ``logger``
+        Optional logger class instance.
+
+        If not specified, defaults to use: ``logging.getLogger("kernel-doc")``
+
+    Note:
+        There are two type of parsers defined here:
+
         - self.parse_file(): parses both kernel-doc markups and
           ``EXPORT_SYMBOL*`` macros;
         - self.process_export_file(): parses only ``EXPORT_SYMBOL*`` macros.
