[PATCH v4 0/5] Add support for the STM32F7 I2C

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




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
