Hello,

I am developing an I2C driver based on the stm32cube LL API.
The driver can be found here: https://github.com/ydamigos/zephyr/tree/i2c_ll_stm32f4

The driver supports both polling and interrupt for master mode.

The status of the I2C driver today is the following:
The master write operation for 7bit addressing was tested on Carbon from 96Boards.
The master read operation was not tested (at the moment I only have a I2C OLED display which supports only write operations)
The 10bit address support was not tested.
Slave mode is not implemented.

Should I open a PR for the driver or wait until all the operations are tested?

Please feel free to test the driver and provide me with any input.

Yannis
