How does this related to the i2c driver for drivers/i2c/busses/i2c-st.c?
Could you have the same piece of hardware do one or the other mode
depending on pin configuration, or is each instance hardwired to
a particular mode?
This is the same IP, that can be configured either in SPI or I2C.
Is there any code worth sharing between the two drivers?
No, except a couple of registers, they are managed in a ways.
The way it is used, a single SSC instance can only be used either in SPI
or I2C mode on a board,
so I think it wouldn't make sense to create a MFD driver to manage it.
