After importing v4.17-rc1 Linux commit 9130ba884640 ("scripts/dtc: Update to upstream version v1.4.6-9-gaadd0b65c987"), sandbox build reports below warnings:

Silent them by applying the 's/_/-/' substitution in the names of the 'fdt_dummy0', 'fdt_dummy1', 'fdt_dummy2', 'fdt_dummy3' properties.
Similar DTC warnings have been recently fixed in Linux kernel, e.g. via v4.17-rc1 commit d366c30d19f4 ("ARM: dts: STi: Fix aliases property name for STi boards").
If done alone, the DTS update generates a failure of the `ut dm fdt_translation` unit test in sandbox environment as seen below:
$ ./u-boot -d arch/sandbox/dts/test.dtb
Applied to u-boot/master, thanks!
