The Linux kernel receives many patches to the devicetree files each release. The hunk header for those patches typically show nothing, making it difficult to figure out what node is being modified without applying the patch or opening the file and seeking to the context. Let's add a builtin 'dts' pattern to git so that users can get better diff output on dts files when they use the diff=dts driver. The regex has been constructed based on the spec at devicetree.org[1] and with some help from Johannes Sixt.

How to write RIGHT test cases ============================= Insert the word "ChangeMe" (exactly this form) at a distance of at least two lines from the line that must appear in the hunk header. The text that must appear in the hunk header must contain the word "right", but in all upper-case, like in the title above. To mark a test case that highlights a malfunction, insert the word BROKEN in all lower-case somewhere in the file. This text is a bit twisted and out of order, but it is itself a test case for the default hunk header pattern. Know what you are doing if you change it. BTW, this tests that the head line goes to the hunk header, not the line of equal signs.
