- * ---------------------------------------------------------------------------
- *
- *  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
