 In general, the format of an address for a device is defined by the
 parent bus type, based on the #address-cells and #size-cells
 properties.  Note that the parent's parent definitions of #address-cells
-and #size-cells are not inhereted so every node with children must specify
+and #size-cells are not inherited so every node with children must specify
 them.  The kernel requires the root node to have those properties defining
 addresses format for devices directly mapped on the processor bus.
