Regarding the 'gpio_keys' device node a dtc reports a couple of warnings: Warning (avoid_unnecessary_addr_size): /gpio_keys: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property Warning (unit_address_vs_reg): /gpio_keys/button@21: node has a unit name, but no reg property The change fixes these issues and adds empty lines between adjacent children device nodes. The device node itself is renamed by substituting an underscore by hyphen to follow the standard naming convention of device tree nodes. Signed-off-by: Vladimir Zapolskiy <vz@mleia.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
