I think this board support should be in separate patch series with
related patches.

I have not seen any related changes in "board-generic.c" for your board.
So just wanted know, how this board is booting ?

I think you should disable modules those are not currently used
as they are enabled by default in omap3.dtsi.

exp:-

&mcbsp2 {
