+ *
+ *  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 must be arrays of
+ *	bus1	3 unsigned integers as follows:
+ *	bus2
+ *	bus3	<id>,<pin>,<od>
+ *
+ *  where:
+ *
+ *  <id>	ID to used as device_id for the corresponding bus (required)
+ *  <sda>	GPIO pin ID of data pin (required)
+ *  <od>	Pin is configured as open drain.
+ *
+ *  See include/w1-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:
+ *
+ *	w1-gpio-custom.bus0
+ *	w1-gpio-custom.bus1
+ *	w1-gpio-custom.bus2
+ *	w1-gpio-custom.bus3
