Good question.

So far there is no well known eval board in mainline that #includes this .dtsi (because it is new) and therefore it passes any compile tests.

  DTC     arch/arm/boot/dts/omap4470-test.dtb - due to target missing
Error: arch/arm/boot/dts/omap4470.dtsi:13.1-5 Label or path sgx not found

I have now added a dummy board (not to be mainlined) for my own compile test...

Indeed. A fix is queued for v8.

BR and thanks,
