V3: Incorporated review comments to set voltage first and then dev group
V2: Incorporated review comments to split the patch and add generic API to set the voltage and device group. http://www.mail-archive.com/u-boot@lists.denx.de/msg27136.html
V1: Added support for 720 Mhz http://www.mail-archive.com/u-boot@lists.denx.de/msg27035.html

Remain consistent with existing naming Use the TWL4030_PM_RECEIVER prefix
Are you sure, you want to do this
VMMC1_VSEL_30
Changed to
TWL4030_PM_RECEIVER_VMMC1_VSEL_30
It looks very awkward to me, More over the prefix is used for register definition already. This is bit value - Kindly confirm
