OMAP2430sdp MMC driver for 2.6.21

Hi Sree,

I saw you enabled SD card successfully on OMAP2430sdp for 2.6.21 on linux-omap mailing list. Did you use the drivers posted by Khasim? Could you please share your patch or give me some hints? I also got the new git kernel, but I can't make SD card work well. I'm blocked here for two weeks. Following is my board's u-boot boot message:

Hi
I didnt used the patch sent by Khasim
I took the virtual Bus support from 2.6.14 kernel
and changed the mmc_2430sdp.c and omap_hsmmc.c as per the 2.6.21 kernel I will send the patch whenever I finished cleaning it..

thanks

Hi,
this may be unrelated but I found that the (not so) recent change in mmc_omap_set_ios() broke SD support on OMAP310. I was digging into the driver maybe two month sago and found that the change made the MMC host send the init sequence to the card far too often during initialisation. Sending it only once or reverting the following commit:

http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=commitdiff;h=46a6730e3ff9add5089ddd007f998b97fb4e8571

made it work better. I haven't posted any information because I had to give up before I managed to make the driver work completely, like it did in 2.6.20. The issue of setting R1 response type instead of R6 and other issues are still unresolved.

Regards

Sorry, this turns out to be completely unrelated to this thread.
