This commit fixes warnings produced by newest in u-boot DTC compiler: 'unnecessary #address-cells/#size-cells without "ranges" or child "reg" property'

I presume the DTSIs are taken from Linux, is this a backport from Linux then ?
Regarding Linux - with Version: DTC 1.4.7-gc86da84d and make W=1 I do not see those warnings as in scripts/Makefile.lib :
# Disable noisy checks by default ifeq ($(findstring 1,$(KBUILD_ENABLE_EXTRA_GCC_CHECKS)),) DTC_FLAGS += -Wno-unit_address_vs_reg \ -Wno-unit_address_format \ -Wno-avoid_unnecessary_addr_size \
those warnings are disabled (-Wno-avoid_unnecessary_addr_size).
On the other hand - in u-boot those warnings are checked (maybe are necessary for OF_PLATDATA correct operation?).
No, keep the DTs synced and fix things upstream (in Linux) if needed, then backport the fixes.
