The min and max voltage levels for the VDD input to DSI were initially set to 2.85V (as suggested by the spec).
We have a platform (db410c) where the same regulator supply is also needed by another consumer at a higher voltage. Bump up the max voltage level to 3.3V. No regressions are seen with this.
