export ARCH=arm64
export W=1
export DT_CHECKER_FLAGS='-v -m'
export DT_SCHEMA_FILES=qcom
export CHECK_DTBS=y
make -j 16 dtbs_check &> dtbs-check.log

export W=1 is the problem. Kernel Makefile differentiates between 'W' being
set from environment and from command line with this check
ifeq ("$(origin W)", "command line")
KBUILD_EXTRA_WARN := $(W)
endif
I assumed similar to DT_SCHEMA_FILES and DT_CHECKER_FLAGS, W will also be
taken. I was not aware of this differentiation, and the 'export W=1' never
came into effect. I re-ran the command as below and see the warnings
$ make W=1 -j 16 dtbs_check &> dtbs-check2.log
$ grep Warning dtbs-check2.log | grep ipq.*dt

Will change pcie@xxx to match with the first reg entry and post the next
version.
