The added include of string.h in libfdt_internal.h breaks the kernel
overriding libfdt_env.h with its own string functions, so it is dropped.
An upstream fix is pending.

Various DT and fwnode functions take a compatible string as a parameter.
These are often used in cases which don't have a driver, so they've been
missed.

The additional checks add about 400 more undocumented compatible
strings.

     never be documented. This will silence various checks warning about
     them.

The 'dt_binding_check' target shouldn't depend on the kernel
configuration, but it has since commit 604a57ba9781 ("dt-bindings:
kbuild: Add separate target/dependency for processed-schema.json").
That is because CHECK_DT_BINDING make variable was dropped, but
scripts/dtc/Makefile was missed. The CHECK_DTBS variable can be used
instead.

Kbuild conventionally uses $(obj)/ for generated files, and $(src)/ for
checked-in source files. It is merely a convention without any functional
difference. In fact, $(obj) and $(src) are exactly the same, as defined
in scripts/Makefile.build:

    src := $(obj)

When the kernel is built in a separate output directory, $(src) does
not accurately reflect the source directory location. While Kbuild
resolves this discrepancy by specifying VPATH=$(srctree) to search for
source files, it does not cover all cases. For example, when adding a
header search path for local headers, -I$(srctree)/$(src) is typically
passed to the compiler.

This introduces inconsistency between upstream and downstream Makefiles
because $(src) is used instead of $(srctree)/$(src) for the latter.

To address this inconsistency, this commit changes the semantics of
$(src) so that it always points to the directory in the source tree.

Going forward, the variables used in Makefiles will have the following
meanings:

  $(obj)     - directory in the object tree
  $(src)     - directory in the source tree  (changed by this commit)
  $(objtree) - the top of the kernel object tree
  $(srctree) - the top of the kernel source tree

Consequently, $(srctree)/$(src) in upstream Makefiles need to be replaced
with $(src).

The iglob function, which we use to find C source files in the kernel
tree, always follows symbolic links. This can cause unintentional
recursions whenever a symbolic link points to a parent directory. A
common scenario is building the kernel with the output set to a
directory inside the kernel tree, which will contain such a symlink.

Instead of using the iglob function, use os.walk to traverse the
directory tree, which by default doesn't follow symbolic links. fnmatch
is then used to match the glob on the filename, as well as ignore hidden
files (which were ignored by default with iglob).

This approach runs just as fast as using iglob.

Add a new flag, '--driver-match', to the dt-extract-compatibles script
that causes it to only print out compatibles that are expected to match
a driver. This output can then be used by tests to detect device probe
failures.

In order to filter the compatibles down to only ones that will match to
a driver, the following is considered:
- A compatible needs to show up in a driver's of_match_table for it to
  be matched to a driver
- Compatibles that are used in both of_match_table and OF_DECLARE type
  macros can't be expected to match to a driver and so are ignored.
  One exception is CLK_OF_DECLARE_DRIVER, since it indicates that a
  driver will also later probe, so compatibles in this macro are not
  ignored.
