/**
* struct of_bus - Callbacks for bus specific translators
+ * @name: A string used to identify this bus in debug output.

+ * to be read, typically "reg".
* @match: Return non-zero if the node whose parent is at
* parentoffset in the FDT blob corresponds to a bus
* of this type, otherwise return zero. If NULL a match
* is assumed.
+ * @count_cells:Count how many cells (be32 values) a node whose parent
+ * is at parentoffset in the FDT blob will require to
+ * represent its address (written to *addrc) & size
+ * (written to *sizec).
+ * @map: Map the address addr from the address space of this
+ * bus to that of its parent, making use of the ranges
+ * read from DT to an array at range. na and ns are the
+ * number of cells (be32 values) used to hold and address
+ * or size, respectively, for this bus. pna is the number
+ * of cells used to hold an address for the parent bus.
+ * Returns the address in the address space of the parent
+ * bus.
+ * @translate: Update the value of the address cells at addr within an
+ * FDT by adding offset to it. na specifies the number of
+ * cells used to hold the address being translated. Returns
+ * zero on success, non-zero on error.

* Each bus type will include a struct of_bus in the of_busses array,
