Looks to me like you're almost all the way there already! :) Much like we're doing with the twl4030 family chips ... they're used on a lot of OMAP3 (and some OMAP2430) boards, and some build dependencies evolved over the past year or so while the driver support was maturing out of mainline. Patches to remove them are ready now, and should be "cooked" enough to make the 2.6.29 merge window. - Dave -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
