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 v3 after Wolfram's review: - Add COMPILE_TEST flag in Kconfig - Use correct driver name in Kconfig i.e i2c-stm32f4 instead of i2c-st - Use more comprehensible name stm32f4_i2c_msg for client specific data - Don't store reset control node as just needed in probe - Use clamp() function to test value between 2 ranges - Use new "i2c_8bit_addr_from_msg() function to build I2C address - Don't write error messages for timeout - Remove error message when i2c_add_adapter() fails as it is already handled by the i2c core driver M'boumba Cedric Madianga (5): dt-bindings: Document the STM32 I2C bindings i2c: Add STM32F4 I2C driver ARM: dts: Add I2C1 support for STM32F429 SoC ARM: dts: Add I2C1 support for STM32429 eval board ARM: configs: Add I2C support for STM32 defconfig .../devicetree/bindings/i2c/i2c-stm32.txt | 33 + arch/arm/boot/dts/stm32429i-eval.dts | 6 + arch/arm/boot/dts/stm32f429.dtsi | 23 + arch/arm/configs/stm32_defconfig | 3 + drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-stm32f4.c | 857 +++++++++++++++++++++ 7 files changed, 933 insertions(+) create mode 100644 Documentation/devicetree/bindings/i2c/i2c-stm32.txt create mode 100644 drivers/i2c/busses/i2c-stm32f4.c -- 1.9.1
