+ * The behaviour of this driver can be altered by setting some parameters

+ *
+ * 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
