Not necessarily.

We often have two interface options for exactly the sam sensor chips. They can be connected
either through SPI or I2C. Which means that there is a core driver for the chip and two different
transport glue components (see e.g. iio/accel/bmc150).

This does not require I2C to be able to handle SPI or vice versa or provide a common API.

And most Bluetooth devices I know have either UART or a direct USB interface. So in the
USB case there is no need to connect it through some USB-UART bridge and treat it as
an UART at all.

Nikolaus
