ARM: OMAP3: mmc-twl4030 voltage cleanup
Correct twl4030 MMC power switching: fix voltage ranges reported
for each slot, and handle them fully.
Lies corrected:
- MMC-1 doesn't support the 2.6-2.7 Volt range
- MMC-2 can't normally support anything except 1.8V
Omissions corrected
- MMC-1 *does* handle the 2.8-2.9 Volt range
- MMC-2 can handle 2.5-3.2 Volt cards, given a transceiver
Add transciever support for MMC-2; enable it for Overo and Pandora.
(Depends on something else to have set up pinmuxing for control
signals instead of as MMC2_DAT4..7 pins.)
Also shrink twl4030_hsmmc_info a smidgeon ... padding is all gone.
