It enables I2C transfer in interrupt mode with Standard-mode, Fast-mode and Fast-mode+ bus speed. --- Version history: v3: * Move stm32f7_i2c_match above stm32f7_i2c_driver * of_device_get_match_data instead of of_match_device * Improve I2C Speed DT gathering * dev_err into dev_dbg for Arbitration loss * Remove useless space aligned v2: * Implement an I2C timings computation algorithm instead of static values(bindings). Algorithm uses generic I2C SCL Falling/Rising bindings and System clock to compute its timings. * I2C Device Tree Update --- Pierre-Yves MORDRET (5): dt-bindings: i2c-stm32: Document the STM32F7 I2C bindings i2c: i2c-stm32f4: use generic definition of speed enum i2c: i2c-stm32f7: add driver ARM: dts: stm32: Add I2C1 support for STM32F746 SoC ARM: dts: stm32: Add I2C1 support for STM32F746 eval board .../devicetree/bindings/i2c/i2c-stm32.txt | 29 +- arch/arm/boot/dts/stm32746g-eval.dts | 8 + arch/arm/boot/dts/stm32f746.dtsi | 22 + drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-stm32.h | 20 + drivers/i2c/busses/i2c-stm32f4.c | 18 +- drivers/i2c/busses/i2c-stm32f7.c | 974 +++++++++++++++++++++ 8 files changed, 1068 insertions(+), 14 deletions(-) create mode 100644 drivers/i2c/busses/i2c-stm32.h create mode 100644 drivers/i2c/busses/i2c-stm32f7.c -- 2.7.4
