Hi Wolfram, I notice that those patches aren't in pull request for 4.14 and not in i2c-next branch. What can we do to progress in this topic? Does issues/remarks still need to be fixed in this code ?

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: 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).
