+ * sets uip per_child_auto_alloc_size to sizeof(struct spi_slave), and the
+ * driver should not override it. Two platform data fields (max_hz and mode)
+ * are copied into this structure to provide an initial value. This allows
+ * them to be changed, since we should never change platform data in drivers.
+ *
+ * If not using driver model, drivers are expected to extend this with
+ * controller-specific data.
+ *
+ * @dev: SPI slave device
+ * @max_hz: Maximum speed for this slave
+ * @mode: SPI mode to use for this slave (see SPI mode flags)
+ * @bus: ID of the bus that the slave is attached to. For
+ * driver model this is the sequence number of the SPI
+ * bus (bus->seq) so does not need to be stored
+ * @cs: ID of the chip select connected to the slave.
+ * @op_mode_rx: SPI RX operation mode.
+ * @op_mode_tx: SPI TX operation mode.
+ * @wordlen: Size of SPI word in number of bits
+ * @max_write_size: If non-zero, the maximum number of bytes which can
+ * be written at once, excluding command bytes.
+ * @memory_map: Address of read-only SPI flash access.
+ * @option: Varies SPI bus options - separate, shared bus.
