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.
