There's a minor error in 3/4 which I've pointed out, it can be fixed in a followup. An error in the conditionals means it's trying to run some of the tests which require an overlay-aware dtc on even when that's not available - I adjusted 4/4 to correct that. It also hit build failures on Travis, because the compiler version there complains about local variables named 'index' shadowing the standard library function. I've corrected that with a followup patch. With that done, the whole lot has been committed to master. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
