-config I2C_GPIO_CUSTOM
- tristate "Custom GPIO-based I2C driver"
- depends on GENERIC_GPIO
- select I2C_GPIO
- help
- This is an I2C driver to register 1 to 4 custom I2C buses using
- GPIO lines.
-
- This support is also available as a module. If so, the module
- will be called i2c-gpio-custom.

- *
- * The behaviour of this driver can be altered by setting some parameters
- * from the insmod command line.
- *
- * The following parameters are adjustable:
- *
- * bus0 These four arguments can be arrays of
- * bus1 1-8 unsigned integers as follows:
- * bus2
- * bus3 <id>,<sda>,<scl>,<udelay>,<timeout>,<sda_od>,<scl_od>,<scl_oo>
- *
- * where:
- *
- * <id> ID to used as device_id for the corresponding bus (required)
- * <sda> GPIO pin ID to used for SDA (required)
- * <scl> GPIO pin ID to used for SCL (required)
- * <udelay> signal toggle delay.
- * <timeout> clock stretching timeout.
- * <sda_od> SDA is configured as open drain.
- * <scl_od> SCL is configured as open drain.
- * <scl_oo> SCL output drivers cannot be turned off.
- *
- * See include/i2c-gpio.h for more information about the parameters.
- *
- * If this driver is built into the kernel, you can use the following kernel
- * command line parameters, with the same values as the corresponding module
- * parameters listed above:
- *
- * i2c-gpio-custom.bus0
- * i2c-gpio-custom.bus1
- * i2c-gpio-custom.bus2
- * i2c-gpio-custom.bus3
