Hi,
My board design that orin controls the output height of the SRC pin of PD FUSB308B through IIC7 (address 0X50). Turn on the load switch and FP2123 outputs a voltage of 5V/1A, and then supplies power to external devices through Type-C.

Add IIC 7 to the device tree，I can’t find dev addr with i2cdetect -r- y 6 .

I check the power is ok with the device fusb308. Is there a problem with the device tree I modified？

Could you confirm with others i2c bus?

I don’t understand what you mean？How do I check this issue？

Hi ShaneCCC,
Is the pin DP0_AUX reuse ？IF DP0_AUX default is display ， how do I change DP0_AUX default display function to I2C mode through the device tree?
Looking forward to your reply！
