HSMMC block transfer (CMD53) doesn't complete

HSMMC block transfer (CMD53) doesn't complete

[Romantic, William]

Hi all,

I'm having a problem with the HSMMC driver.  If I attempt to send data
that amounts to less than the current SDIO block size, the transfer
never completes.  If set my block size to a value that's less than the
smallest amount of data that I intend to send, the driver properly
breaks it into blocks, sends them, and completes.

I did see a couple e-mails in the archives that look like they may be
talking about the same issue.  As far as I can tell though, they haven't
been resolved.

I'm using the OMAP35x evm, the Libertas driver, and a Marvel sd8686 WiFi
radio.  I currently have everything running with some workarounds and
I'm looking to properly resolve the issues.

Thank - You
William Romantic

Is anyone else working on fixing up HSMMC SDIO, or are there any partial 
patches waiting in the wings?  Bill's work is going to generate patches 
for the list's review over the next couple of weeks.  It would be a 
shame to duplicate effort unnecessarily, or at least not to collaborate 
if duplication helps us get something out faster.

Hi,

We working on SDIO solution on OMAP35x EVM for Marvel sd 8686 (Libertas driver). We will plan to push SDIO support in near future.
