>   In igepV5 the LDO7 is connected to:
>     VDDA_DSIPORTA - ball AA33
>     VDDA_DSIPORTC - ball AE33
>     VDDA_HDMI - ball AN25
>   LDO4 is connected to:
>     VPP1 - ball AD9

Thanks for the info, here's an updated patch with comments and now
using 1.8V instead of the 2.0V omap5-board-common.dtsi.

Regards,

Tony
