Shouldn't it be remembering what voltage it was using,
and then restore that, instead of always making MMC1
restart at a 3.0V level? That's pretty awkward to test
unless you have a 1.8V-capable card in MMC1...
Somewhat related: I think the PBIAS register updates
should be moved out of mach-omap2/mmc-twl4030.c into
this driver. They're needed no matter what flavor
regulator is used to with MMC1 voltage over 1.8V,
and it's a bit odd to split the state machine for
1.8V -vs- 3.0V I/O voltages the way it's now done.
