/** * struct i2c_gpio_platform_data - Platform-dependent data for i2c-gpio * @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. * @sda_is_output_only: SDA output drivers can't be turned off. * This is for clients that can only read SDA/SCL. * @sda_has_no_pullup: SDA is used in a non-compliant way and has no pull-up. * Therefore disable open-drain. * @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. * @scl_has_no_pullup: SCL is used in a non-compliant way and has no pull-up. * Therefore disable open-drain.
