I2C support for 8541

Assuming I have the external IRQ's understood, the next issue is the
hardware clock on our board with the linux-2.6.17.11 kernel. We are
using a "DS1338U", which is an I2C RTC.

I am trying to identify the relevant source for the 8541/8555 I2C
interface in the source base which reads/writes I2MOD, I2ADD, II2BRG,
I2COM, I2CER & I2CMR.

I can find a few references to MPC85xx_CPM_I2C in
../syslib/mpc85xx_devices.c, but nothing close in drivers/i2c/...

Can someone help me understand the completeness of the I2C source in the
2.6.17.11 kernel, please.
