Hi,
I am trying to implement card-detect and regulator changes for HSMMC
driver on OMAP4.
In OMAP4, hsmmc doesn't use any gpio line for card detect and instead
uses interrupt line
from TWL6030 which also provides a register for
status[Inserted/removed] of the removable Card.
Currently all the gpio related stuff moved from board file "hsmmc.c"
to driver file "omap_hsmmc.c"
[http://marc.info/?l=linux-mmc&m=126369200005981&w=2]and since the
card-detect implementation
for twl6030 uses I2c read/write it doesn't make sense to have the
card-detect implementation in board file.
And the regulator changes can remain in driver file.
Regards,
Kishore

Does it make sense to have the gpio and non-gpio related stuff for
card detect
in board file?
Any suggestions appreciated.
