This patchset adds support for the I2C controller embedded in STM32F7xx SoC.
It enables I2C transfer in interrupt mode with Standard-mode, Fast-mode and
Fast-mode+ bus speed.
---
Version history:
v4:
* Fix max I2C Bus clock to 100%
* Solve typo issue
* Add retries value
v3:
* Move stm32f7_i2c_match above stm32f7_i2c_driver
* of_device_get_match_data instead of of_match_device
* Improve I2C Speed DT gathering
* dev_err into dev_dbg for Arbitration loss
* Remove useless space aligned
v2:
* Implement an I2C timings computation algorithm instead of static
values(bindings). Algorithm uses generic I2C SCL Falling/Rising
bindings and System clock to compute its timings.
* I2C Device Tree Update
