| * I2C controller embedded in STMicroelectronis STM32 platforms |
| |
| Required properties : |
| - compatible : Must be "st,stm32f7-i2c" |
| - reg : Offset and length of the register set for the device |
| - resets: Must contain the phandle to the reset controller |
| - clocks: Must contain the input clock of the I2C instance |
| - A pinctrl state named "default" must be defined to set pins in mode of |
| operation for I2C transfer |
| - #address-cells = <1>; |
| - #size-cells = <0>; |
| |
| Optional properties : |
| - clock-frequency : Desired I2C bus clock frequency in Hz. If not specified, |
| the default 100 kHz frequency will be used. As only Normal, Fast and Fast+ |
| modes are implemented, possible values are 100000, 400000 and 1000000. |
| |
| Example : |
| |
| i2c1: i2c@40005400 { |
| compatible = "st,stm32f7-i2c"; |
| reg = <0x40005400 0x400>; |
| resets = <&rcc 181>; |
| clocks = <&clk_pclk1>; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&pinctrl_i2c1>; |
| clock-frequency = <400000>; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| }; |
