Hi,
I'm trying to figure out why the broken write transfer tests in mmc_test
require the result to be -ETIMEDOUT, so that I can make dw_mmc pass

There are several situations when dw_mci_submit_data_dma() decides to
fall back to PIO mode instead of using DMA, due to a short (to avoid
overhead) or complex (e.g. with unaligned buffers) transaction, even
though host-use_dma is set. However dw_mci_stop_dma() decides whether

Remove error messages for timeout and CRC failure, since the error code
already indicates the problem.

When a data write isn't acknowledged by the card (so no CRC status token
is detected after the data), the error -EIO is returned instead of the
-ETIMEDOUT expected by mmc_test 15 - Correct xfer_size at write (start
failure) and 17 Correct xfer_size at write (midway failure). In PIO
mode the
If an error occurs mid way through a transaction (such as a missing CRC
status response after the 2nd block written out of 3), then the FIFO may
still contain data which will interfere with the next transaction.
Therefore after an error has been detected, reset the fifo using the
CTRL register.
So wlan probe function should be called for re-downloading, is it be
achieved by calling pm_runtime_get_sync and mmc_power_restore_host?
Not really;
I assume you refer to libertas_sdio, which AFAICT, is built to power
on the device (and configure it) on -probe(), and then power it off
on

Hi Philip..
If i didn't set MMC_CAP_BUS_WIDTH_TEST,
entered mmc_compare_ext_csds(). right?
i understand that mmc_compare_ext_csds() compared with previously ext_csd.
But in source code, always previously ext_csd is NULL.
I didn't find where assigned ext_csd..
I think that need to assign
