I am in the process of starting a board with an STM32MP153CAB processor, unfortunately due to an error in the design, the I2C4 interface is not available( i2c4 is connected to the PMIC by default). I am able connect I2C2 directly to the PMIC, but this interface is not supported in TF-A, other solution is connect I2C6 using wires. The question is how to force using of i2c6 or i2c2 instead of I2C4 by dts config files (Yocto kikrcore).

Hi @markhg
Guideline to change I2C instance for PMIC is present in PMIC hardware components - stm32mpu-ecosystem-v4
Hope it help
