the default 100 kHz frequency will be used.
For STM32F4 SoC Standard-mode and Fast-mode are supported, possible values are
100000 and 400000.
For STM32F7 SoC, Standard-mode, Fast-mode and Fast-mode Plus are supported,
possible values are 100000, 400000 and 1000000.
- i2c-scl-rising-time-ns: Only for STM32F7, I2C SCL Rising time for the board
(default: 25)
- i2c-scl-falling-time-ns: Only for STM32F7, I2C SCL Falling time for the board
(default: 10)
For STM32F7, STM32H7 and STM32MP1 SoCs, Standard-mode, Fast-mode and Fast-mode
Plus are supported, possible values are 100000, 400000 and 1000000.

- i2c-scl-falling-time-ns: I2C SCL Falling time for the board (default: 10)
For STM32F7, STM32H7 and STM32MP1 only.
I2C Timings are derived from these 2 values
- st,syscfg-fmp: Only for STM32F7, use to set Fast Mode Plus bit within SYSCFG
whether Fast Mode Plus speed is selected by slave.
- st,syscfg-fmp: Use to set Fast Mode Plus bit within SYSCFG when Fast Mode
Plus speed is selected by slave.
1st cell: phandle to syscfg
2nd cell: register offset within SYSCFG
3rd cell: register bitmask for FMP bit
For STM32F7, STM32H7 and STM32MP1 only.
