1* I2C controller embedded in STMicroelectronis STM32 platforms
2
3Required properties :
4- compatible : Must be "st,stm32f7-i2c"
5- reg : Offset and length of the register set for the device
6- resets: Must contain the phandle to the reset controller
7- clocks: Must contain the input clock of the I2C instance
8- A pinctrl state named "default" must be defined to set pins in mode of
9  operation for I2C transfer
10- #address-cells = <1>;
11- #size-cells = <0>;
12
13Optional properties :
14- clock-frequency : Desired I2C bus clock frequency in Hz. If not specified,
15  the default 100 kHz frequency will be used. As only Normal, Fast and Fast+
16  modes are implemented, possible values are 100000, 400000 and 1000000.

20	i2c1: i2c@40005400 {
21		compatible = "st,stm32f7-i2c";
22		reg = <0x40005400 0x400>;
23		resets = <&rcc 181>;
24		clocks = <&clk_pclk1>;
25		pinctrl-names = "default";
26		pinctrl-0 = <&pinctrl_i2c1>;
27		clock-frequency = <400000>;
28		#address-cells = <1>;
29		#size-cells = <0>;
