This patch series extend the existing I2C functionality with:
- Abstractions allowing to implement I2C algorithms used by I2C adapters;
- Abstractions allowing to create and add new I2C adapters;
- Safe wrappers upon I2C and SMbus transferring C API: read/write
bytes/words/byte arrays.
The patch series contains additional new sample driver `rust_i2c_adapter`
presenting the new functionality.
Patch series depend on
