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 .../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 | 883 +++++++++++++++++++++ 7 files changed, 959 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
