I tried running the tool again, and it nicely re-ordereed the new imx8mm-hummingboard-ripple.dts

Yet it crashes on imx8mn-solidsense-n8-compact.dts:

❯ ./dt-format /opt/workspace/linux/arch/arm64/boot/dts/freescale/imx8mn-solidsense-n8-compact.dts
terminate called after throwing an instance of 'std::out_of_range'
  what():  basic_string::substr: __pos (which is 26) > this->size() (which is 18)
[1]    12030 IOT instruction (core dumped)  ./dt-format

Then I ran it on the iiot board dts and dtso, and it suggests one particular change I was not expecting:

-&{/} {
+& {};
+
+/ {

❯ find . -iname "*.dtso" -exec grep -H "&{/}" {} \; | wc -l
110

❯ find . -iname "*.dtso" -exec grep -H "/ {" {} \; | wc -l
15

Which one is preferred going forward?
