Hi all,
We have added the device tree source code for the USB3803 hub controller on the Colibri iMX8X module. it looks like there is an issue with the registration of the USB3803 I2C client.
The error message “Failed to register i2c client usb3803 at 0x08 (-16)” suggests that the I2C driver was unable to register the device with the I2C bus at address 0x08.
Attached the patch and error log below. Kindly help on this issue.
Thank you in advance.
