* @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.
