* 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
+ * be accessed using dev_get_parent_priv() 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
* @dev: SPI slave device
* @max_hz: Maximum speed for this slave
* @mode: SPI mode to use for this slave (see SPI mode flags)
+ * @speed: Current bus speed. This is 0 until the bus is first
+ * claimed.
* @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
