Hi,
> How i can figure out whether this mechanism will be provided of my driver?
Use i2c_get_functionality() and check for
I2C_FUNC_SMBUS_READ_BLOCK_DATA (or look at the source code).
> What is the alternative of using the function i2c_smbus_read_block_data?
That depends solely on your slave device. Check the documentation what
transfer types it supports and what alternatives are possible.
Regards,
Wolfram
