This doesn't show as a proper cherry-pick from devicetree-rebasing tree,
following fails for me:

$ ./tools/update-subtree.sh pick dts 6a36dca4375fce51b627f5a985a79fc8b8bd7f55
>From https://git.kernel.org/pub/scm/linux/kernel/git/devicetree/devicetree-rebasing
 * branch                    master     -> FETCH_HEAD
fatal: bad object 6a36dca4375fce51b627f5a985a79fc8b8bd7f55

Has this patch landed in Linux mainline?

Ditto for all the subsequent patches in this series.
