* struct of_bus - Callbacks for bus specific translators
|
|
|
+ * @name: A string used to identify this bus in debug output.
|
|
|
+ * @addresses: The name of the DT property from which addresses are
|
|
|
+ * 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.
