1 * I2C controller embedded in STMicroelectronics STM32 I2C platform
4 - compatible : Must be one of the following
5 - "st,stm32f4-i2c"
6 - "st,stm32f7-i2c"
7 - reg : Offset and length of the register set for the device
8 - interrupts : Must contain the interrupt id for I2C event and then the
9 interrupt id for I2C error.
10 - resets: Must contain the phandle to the reset controller.
11 - clocks: Must contain the input clock of the I2C instance.
12 - A pinctrl state named "default" must be defined to set pins in mode of
13 operation for I2C transfer
14 - #address-cells = <1>;
15 - #size-cells = <0>;
18 - clock-frequency : Desired I2C bus clock frequency in Hz. If not specified,
20 For STM32F4 SoC Standard-mode and Fast-mode are supported, possible values are
22 For STM32F7 SoC, Standard-mode, Fast-mode and Fast-mode Plus are supported,
24 - i2c-scl-rising-time-ns : Only for STM32F7, I2C SCL Rising time for the board
26 - i2c-scl-falling-time-ns : Only for STM32F7, I2C SCL Falling time for the board
28 I2C Timings are derived from these 2 values
