Title:
Failure to detect i2c device on Mering
Status in Kernel SRU Workflow:
New
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Jammy:
Fix Released
Bug description:
Mering failed to detect any I2C devices when running the
i2c_driver_test.py device test. This issue occurred despite the
expectation of detecting at least one I2C device on any I2C bus.
Test steps in i2c_driver_test.py:
1. run `i2cdetect -l` to list all the detected buses
2. run `i2cdetect -y -r` on each bus to check if there is any i2c devices
Expect log:
```
Detected buses: ['0', '1', '2', '3', '4', '5']
Checking I2C bus 0
0 1 2 3 4 5 6 7 8 9 a b c d e f
