First Dual I2C Controller : 0x1180000 (first i2c bus), 0x1181000(second I2C bus) Second Dual I2C Controller : 0x1190000 (third i2c bus), 0x1191000(fourth I2C bus) My understanding is CONFIG_SYS_FSL_I2C_OFFSET is offset for first I2C controller and CONFIG_SYS_FSL_I2C2_OFFSET is offset for second I2C controller. Have you checked for dual I2C controller, CONFIG_SYS_FSL_I2C2_OFFSET implies offset for second I2C bus, not the controller?
