Looks good to me.

I did not use your tree (based on 4.5-rc1) to test.  I instead based on
4.4 and did ./scripts/dtc/update-dtc-source.sh with the current dtc git
tree and verified the commits in the dtc tree matched the list above.

I compiled all of the .dts files in the Linux source tree.  I diffed the
resulting .dtb files against the .dtb files created before updating dtc.
There were no differences.

I visually inspected all of the commits you listed in the dtc tree.
