I've run the mmc-test kernel module with this driver on our TX28
module which fails in the following tests:
|mmc0: Test case 15. Correct xfer_size at write (start failure)...
|mmc0: Result: ERROR (-110)
|mmc0: Test case 16. Correct xfer_size at read (start failure)...
|mmc0: Result: ERROR (-110)
|mmc0: Test case 17. Correct xfer_size at write (midway failure)...
|mmc0: Result: ERROR (-110)
|mmc0: Test case 18. Correct xfer_size at read (midway failure)...
|mmc0: Result: ERROR (-110)

Could you try the test on your hardware?


Best regards,
