Could anybody please give a hint - which kernel-defined i2c objects, and how
many of them, I need to define and use to substitute these driver-defined
functions i2c_read(), i2c_write() ?
In a word, there's 4 chips with different addresses, to which this code
communicates via main chip's dedicated registers.
Do i need a single i2c_adapter or several?
Do i need i2c_client entities?
where should I put what is named "devid" here?

Thanks in advance.

It depends how those are connected at hardware level. Quickly looking I think "devid" is here to select proper I2C adapter. So I think there is 4 I2C adapters and each of those adapter has 1 slave device. Is that correct? If yes, then register 4 I2C adapters and register single client for each of those adapters.
