[PATCH 00/16] arm64: dts: exynos: Format with dtfmt

[PATCH 00/16] arm64: dts: exynos: Format with dtfmt

[Waqar Hameed]

I was looking through the notes for the last Devicetree microconference
at Linux Plumbers (LPC) 2025 [1], and realized that the tool I have been
working on might be of interest here: dtfmt - a Devicetree Source
formatter [2].

dtfmt uses a parser with lexical grammar (tree-sitter) directly ported
from the actual Device Tree Compiler's (dtc) lexer/parser, also
(hand)written by me [3]. It is primarily designed for the Linux kernel
and currently parses all 6872 devicetree files in the tree successfully
(found with `find . -iregex ".+\.dts[io]?$"`).

This tool was developed out of frustration when reviewing devicetree
patches internally at my company Axis. I would have published it earlier
if I was aware of the on-going discussions at LPC 2025. It only caught
my attention since I'm planning to attend LPC this year (especially the
Devicetree microconference and would therefore love to discuss this more
in-person!).

This patch series is only a small demonstration of dtfmt. Obviously one
can run dtfmt for all files and generate a much bigger diff, but I just
chose `arch/arm64/boot/dts/exynos/` here. Primarily to get Krzysztof in
the "To:"-field :)

Please note that since we don't currently have a _definitive_ style
guide for Devictree Source files, dtfmt tries to be pragmatic and try to
"guess" the intended style (e.g. alignment of arrays and comma separated
property data). Some things have been left out (for now), because it's
too hard to implement without any concrete style decisions in place
(e.g. alignment of comments, long line wrapping etc.). dtfmt will
continue to develop and will always align with the Linux kernel.
Feedback (and collaboration) is therefore greatly appreciated!
