Detailed Description

struct i2c_gpio_platform_data - Platform-dependent data for i2c-gpio : GPIO pin ID to use for SDA : GPIO pin ID to use for SCL : signal toggle delay. SCL frequency is (500 / udelay) kHz : clock stretching timeout in jiffies. If the slave keeps SCL low for longer than this, the transfer will time out. : 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 set up as open drain. Same requirements as for sda_is_open_drain apply. : SCL output drivers cannot be turned off.
