omap: TWL4030 Bump VMMC1 interface voltage from 3V to 3.15V
MMC interfaces are specified to be 3.3V compatible with an operating voltage range of 3.1V to 3.5V for SD cards. This change affects hardware using TWL4030 (TPS6595x) PMICs and should improve the reliability when communicating with marginally-spec'd MMC devices. 3.15V is the highest possible level for this chip. This patch has been tested on a Gumstix Overo board. Signed-off-by: NAsh Charles <ash@gumstix.com> Tested-by: NSteve Sakoman <steve@sakoman.com>
