+		CONFIG_I2C_MULTI_BUS
+
+		This option allows the use of multiple I2C buses, each of which

+		Note that bus numbering is zero-based.

+		CFG_I2C_NOPROBES
+
+		This option specifies a list of I2C devices that will be skipped
+		when the 'i2c probe' command is issued (or 'iprobe' using the legacy
+		command).  If CONFIG_I2C_MULTI_BUS is set, specify a list of bus-device
+		pairs.  Otherwise, specify a 1D array of device addresses
