Subject: [PATCH v2 13/14] OMAP3: Add voltage dependency table for VDD1.

In OMAP3, for perfomrance reasons when VDD1 is at voltage above 1.075V, VDD2 should be at 1.15V for perfomrance reasons. This patch introduce this cross VDD dependency for OMAP3 VDD1.

Dependency table for 3630 is missing. Pls add the same.
Also voltage values for 3630 does not match those on OPP table. Pls align them.
