David Brownell eb25082657 omap_hsmmc: only MMC1 allows HCTL.SDVS != 1.8V ... Based on a patch from Tony Lindgren ... after initialization, never change HCTL.SDVS except for MMC1. The other controller instances only support 1.8V in that field, although they can suport other card/SDIO/eMMC/... voltages with level shifting solutions such as external transceivers. MMC2 behavior sanity tested on Overo/WLAN, OMAP3430 SDP, and custom hardware. MMC1 also sanity tested on those platforms plus Beagle. This also fixes a bug preventing MMC2 (and also presumably MMC3) from powering down when requested.
