Hmm don't you still need to keep omap4-var-som.dts to build just the
core SoC module without any add-on boards?

Also, you might want to use the OMAP4_CORE_IOPAD and OMAP4_WKUP_IOPAD
macros in include/dt-bindings/pinctrl/omap.h to be able to check the
registers against the TRM easier as you can use the physical register
offset listed in the TRM.
