+ * struct spi_slave - Representation of a SPI slave
+ *
+ * For driver model this is the per-child data used by the SPI bus. It can
+ * be accessed using dev_get_parentdata() on the slave device. The SPI uclass
+ * 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
