st,stm32-i2c-v1¶

Description¶

These nodes are “i2c” bus nodes.

STM32 I2C V1 controller

Properties¶

Properties not inherited from the base binding file.

Name

Type

Details

pinctrl-0

phandles

GPIO pin configuration for serial signals (SDA, SCL).  We expect
that the phandles will reference pinctrl nodes.

For example the I2C1 would be
   pinctrl-0 = <&i2c1_sda_pb11 &i2c1_scl_pb10>;

clock-frequency

int

Initial clock frequency in Hz

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “st,stm32-i2c-v1” compatible.
