Normally i2c controller works as master, so slave addr is not needed, or it will impact some slave device (eg. ST NFC chip) i2c accesses, because it has the same i2c address with controller. For example, On the pxa1928 based platform, where PMIC (88pm860) is present @0x30 address on TWSI0 interface, and if we set 0x30 as a slave address in pxa1928 TWSI0 module, all the transactions towards PMIC would go for toss.
