CONFIG_OMAP_PM_NOOP is defined. The build breakage is due to a missing header inclusion. I just sent a patch for this [1] There are still a couple of patches missing before omap2plus_defconfig compiles https://patchwork.kernel.org/patch/1810481/ https://patchwork.kernel.org/patch/1810441/ I guess they are on the way from some other tree.
