50 * devfdt_get_addr_index() - Get the indexed reg property of a device
52 * @dev: Pointer to a device
53 * @index: the 'reg' property can hold a list of <addr, size> pairs

63 * Returns the address and size specified in the 'reg' property of a device.

66 * @index: the 'reg' property can hold a list of <addr, size> pairs
67 * and @index is used to select which one is required

80 * @name: the 'reg' property can hold a list of <addr, size> pairs, with the
