Subject: [PATCH v2 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 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
