22 * @bus_num: The bus number to use (if possible).

24 * @slave_addr: The I2C address for the slave device (if enabled).
25 * @frequency: The desired frequency in Hz of the bus. This is
26 * guaranteed to not be exceeded. If the caller does
27 * not care, use zero and the driver will select a
28 * useful default.
29 * @sda_delay: The delay (in ns) applied to SDA edges.
30 * @cfg_gpio: A callback to configure the pins for I2C operation.
