davinci_mmc issues on kernel 3.17.0

[Angelo Dureghello <angelo70@gmail.com>]

Dear all,

i am moving from a working 3.5.1 kernel to the 3.17.0.
My system is am1808 (ti arm) based, and i access a 4 data
wires microsd card.

mmc access is not working properly anymore on kernel
3.17.0

For example, trying a simple mkfs.ext3 on the mmc card, verifying
just after with fsck.ext3, i get several errors. Similarly, i get errors
if i use ext2, ext4 or fa.

See below:

Clear<y>?
.... (continue)


I am suspecting of a mmc driver issue, or, something new to be set
from my board.c.

I also strangely see different inodes number, in kernel 3.5.1 are double.

hope in some help,

Regards,
angelo
