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