Subject: Warning when compiling DTB on X-Gene platform with dtc 1.4.1-g53bf130b

Hi Rob,

I got warning on unit_address_vs_reg similar to this
https://lkml.org/lkml/2016/3/7/43 when using v4.7-rc2 dtc to build dtb
for X-Gene Mustang:

dhdang@...ne-next=>./scripts/dtc/dtc -O dtb -R 16 -o mustang.dtb
arch/arm64/boot/dts/apm/apm-mustang.dts
  Warning (unit_address_vs_reg): Node /soc/reboot@...00014 has a unit
name, but no reg property
  Warning (unit_address_vs_reg): Node /memory has a reg or ranges
property, but no unit name
  Warning (unit_address_vs_reg): Node /gpio-keys/button@1 has a unit
name, but no reg property

There are nodes that I cannot change the node-name due to backward
compatible with old firmware reason (/soc/reboot@...00014 as an
example). Is there any other way to avoid the warning?

Regards,
Duc Dang.
