- 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
+ whether 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
Example :
clocks = <&rcc 1 CLK_I2C1>;
pinctrl-0 = <&i2c1_sda_pin>, <&i2c1_scl_pin>;
pinctrl-names = "default";
+ st,syscfg-fmp = <&syscfg 0x4 0x1>;
