Subject: [PATCH v9 0/5] Add support for the STM32F4 I2C

This patchset adds support for the I2C controller embedded in STM32F4xx SoC.
It enables I2C transfer in interrupt mode with Standard-mode and Fast-mode bus
speed.

Changes since v8:
- Rework I2C Clock Control Register computation (Uwe)
- Save register accesses as often as possible (Uwe)
- Don't use mask before saving rx buffer (Uwe)
- Add more comments to explain hardware way of working (Uwe)
- Rename stm32f4_i2c_handle_rx_btf function by stm32f4_i2c_handle_rx_done (Uwe)
- Set/Clear Ack position bit during address match phase

M'boumba Cedric Madianga (5):
  dt-bindings: Document the STM32 I2C bindings
  i2c: Add STM32F4 I2C driver
  ARM: dts: stm32: Add I2C1 support for STM32F429 SoC
  ARM: dts: stm32: Add I2C1 support for STM32429 eval board
  ARM: configs: stm32: Add I2C support for STM32 defconfig
