From: Patrice Chotard <patrice.chot...@st.com>Add i2c driver which can be used on both STM32F7 and STM32H7. This I2C block supports the following features: _ Slave and master modes _ Multimaster capability _ Standard-mode (up to 100 kHz) _ Fast-mode (up to 400 kHz) _ Fast-mode Plus (up to 1 MHz) _ 7-bit and 10-bit addressing mode _ Multiple 7-bit slave addresses (2 addresses, 1 with configurable mask) _ All 7-bit addresses acknowledge mode _ General call _ Programmable setup and hold times _ Easy to use event management _ Optional clock stretching _ Software reset Signed-off-by: Christophe Kerello <christophe.kere...@st.com> Signed-off-by: Patrice Chotard <patrice.chot...@st.com> --- v2: _ add I2C controller description in Kconfig _ rename stm32_i2c_dev struct to stm32_i2c_priv _ add comment for stm32_i2c_handle_reload() _ split stm32_i2c_compute_timing() code and add : _ stm32_i2c_compute_solutions() which computes list of possible timings candidate _ stm32_i2c_choose_solution() which selects the best timing _ use #defines instead of hard coded vlaue for speed in stm32_i2c_set_bus_speed() and in i2c_specs[] array _ move part of code of stm32_i2c_probe() inside stm32_ofdata_to_platdata() doc/device-tree-bindings/i2c/i2c-stm32.txt | 30 + drivers/i2c/Kconfig | 20 + drivers/i2c/Makefile | 1 + drivers/i2c/stm32f7_i2c.c | 882 +++++++++++++++++++++++++++++ 4 files changed, 933 insertions(+) create mode 100644 doc/device-tree-bindings/i2c/i2c-stm32.txt create mode 100644 drivers/i2c/stm32f7_i2c.c
