- interrupts: Must contain the interrupt id for I2C event and then the
interrupt id for I2C error.
- resets: Must contain the phandle to the reset controller.

Optional properties:
- clock-frequency: Desired I2C bus clock frequency in Hz. If not specified,
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
- 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
- i2c-scl-falling-time-ns: Only for STM32F7, I2C SCL Falling time for the board
(default: 10)
I2C Timings are derived from these 2 values
- st,syscfg-fmp: Only for STM32F7, use to set Fast Mode Plus bit within SYSCFG
- st,syscfg-fmp: Only for STM32F7, use to set Fast Mode Plus bit within SYSCFG
whether Fast Mode Plus speed is selected by slave.
