[PATCH 0/4] mmc: host: tmio: properly report status from autocmd12

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



SDHI automatically sends CMD12 when the desired amount of data was transferred
after multi block commands. However, the response from that CMD12 was never
reported back to the mmc core, so that errors like ECC might go unnoticed. This
series aims to fix that and clean up minor issues on the way when dealing with
the autocmd12 feature. So far, I could only test that the success case was
reported back to the MMC core [1]. An error case (like ECC) could not be
created yet, but I will keep on trying. However, the initial flaw of the CMD12
response not reported back is fixed with this series as the success case
demonstrates. If an ECC error is not properly handled, it is a seperate issue
anyway. So, I think this series could go in now. No pressure for 4.11, though.
But would be nice, of course ;)

The patches are based on mmc-next. A branch can be found here:
