| Subject | [PATCH v3 0/5] Add support for the STM32F4 I2C |
| Message-ID | <rMaff-27F-13@gated-at.bofh.it> |
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 v2: - Group I2C pins definitions in the device tree (Maxime) - Suffix I2C phandle with part number (Maxime) - Remov busy variable as not used (Rajeev) - Rename STM32F4_I2C_TRISE_TRISE macro (Rajeev) - Remove magic number during rise time computation (Rajeev) - Simplify speed mode function computation 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 | 22 + arch/arm/configs/stm32_defconfig | 3 + drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-stm32f4.c | 863 +++++++++++++++++++++ 7 files changed, 938 insertions(+) create mode 100644 Documentation/devicetree/bindings/i2c/i2c-stm32.txt create mode 100644 drivers/i2c/busses/i2c-stm32f4.c -- 1.9.1
