+  Report driver source files that match the compatibles in the device
+  tree file and the kernel config options that enable the driver source
+  files.
+
+  This program must be run in the root directory of a Linux kernel
+  source tree.
+
+  The default format is a report that is intended to be easily human
+  scannable.
+
+  An alternate format can be selected by --config-format.  This will
+  create output that can easily be edited to create a fragment that can
+  be appended to the existing kernel config file.  Each entry consists of
+  multiple lines.  The first line reports flags, the node path, compatible
+  value, driver file matching the compatible, configuration options, and
+  current values of the configuration options.  For each configuration
+  option, the following lines report the current value and the value that
+  is required for the driver file to be included in the kernel.
+
+  If a large number of drivers or config options is listed for a node,
+  and the '$pr_flag_value[$pr_flag_pos_hard_coded]' flag is set consider using --white-list-config and/or
+  --white-list-driver.  If the white list option suppresses the correct
+  entry please report that as a bug.
+
+  CAUTION:
+     This program uses heuristics to guess which driver(s) support each
+     compatible string and which config option(s) enables the driver(s).
+     Do not believe that the reported information is fully correct.
+     This program is intended to aid the process of determining the
+     proper kernel configuration for a device tree, but this is not
+     a fully automated process -- human involvement may still be
+     required!
+
+     The driver match heuristic used is to search for source files
+     containing the compatible string enclosed in quotes.
+
+     This program might not be able to find all drivers matching a
+     compatible string.
+
+     Some makefiles are overly clever.  This program was not made
+     complex enough to handle them.  If no config option is listed
+     for a driver, look at the makefile for the driver source file.
+     Even if a config option is listed for a driver, some other
+     available config options may not be listed.
