This patch set unflattens device trees when running DT's unittest. It is a follow up to https://www.spinics.net/lists/linux-kselftest/msg05454.html part of the KUnit RFC v3 thread (https://www.spinics.net/lists/linux-kselftest/msg05431.html). Rob asked me to submit this patch separately along with some modifications. -- 2.20.1.791.gb4d0f1c61a-goog
