I've looked a little more deeply into this and I'm not entirely
convinced that what you claim is true. It seems that the only dependency
that the MMC module _might_ have on the TWL4030 is for the LDOs, which I
believe should be covered in the regulator driver, not GPIO.

In light of this, I think the use of the TWL's GPIO lines for MMC it
might be a board specific design decision. In the case of the
Beagleboard, they are only TWL GPIO used by the MMC configuration is for
.gpio_cd but as far as I could see they could have chosen any GPIO for
this. Am I missing something?

Cheers,
