Hi Ohad,

The regulator is only enabled once. Equally, the MMC interface is
initialised only at boot, and remains untouched afterwards. It's
config doesn't change:

clock:		25000000 Hz
vdd:		7 (1.65 - 1.95 V)
bus mode:	2 (push-pull)
chip select:	0 (don't care)
power mode:	2 (on)
bus width:	2 (4 bits)
timing spec:	0 (legacy)

Full kernel log (rather large): http://130.89.163.61/dmesg

What concerns me is the regulator config - most boards seem to call
the fixed regulator vmmc, but I require VSIM as well to power the card
(which requires it to be labeled vmmc for the mmc subsystem?).
