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 v1: - use compatible st,stm32f4-i2c instead of st,i2c-stm32f4 (Rob) - fix typo s/enmpty/empty (Maxime) - use one function to handle TX fifo empty and byte xfer finished IT (Maxime) - set duty cycle in timing struct in Fast mode - Rework clock management (call prepare/unprepare at probe and remove, call clk_enable/clk_disable for each I2C transfer) 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 | 24 + arch/arm/configs/stm32_defconfig | 3 + drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-stm32f4.c | 867 +++++++++++++++++++++ 7 files changed, 944 insertions(+) create mode 100644 Documentation/devicetree/bindings/i2c/i2c-stm32.txt create mode 100644 drivers/i2c/busses/i2c-stm32f4.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
