+ * @udelay: signal toggle delay. SCL frequency is (500 / udelay) kHz
+ * @timeout: clock stretching timeout in jiffies. If the slave keeps
+ *	SCL low for longer than this, the transfer will time out.
+ * @sda_is_open_drain: SDA is configured as open drain, i.e. the pin
+ *	isn't actively driven high when setting the output value high.
+ *	gpio_get_value() must return the actual pin state even if the
+ *	pin is configured as an output.
+ * @scl_is_open_drain: SCL is set up as open drain. Same requirements
+ *	as for sda_is_open_drain apply.
+ * @scl_is_output_only: SCL output drivers cannot be turned off.
