Hi all,
yamldt has a new minor release out (v0.3)
The last minor release brought schema validation, and this one
bring dts2yaml an automatic DTS to YAML conversion tool.
The test-suite converts and compiles all the current DTS files in
the kernel and out of the 1.3 thousand DTS files only 6 fail to
convert (due to complex macro usage that make the source file look
nothing like DTS).
Conversion is extremely simple:
$ dts2yaml -r bcm2837-rpi-3-b.dts
Will convert the rpi-3 DTS file (and all the included files).
$ ls *.yaml*
