I did not ask for compaction into one continued line but for proper indentation. Having one entry per one line was fine because you have really a lot of entries and it was making things easier to check. It should look like: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/exynos54xx.dtsi?h=v4.20#n78 Best regards, Krzysztof
