Right now, a little less than half of the .dts* files
have an author or other email address in them.

$ git ls-files arch/arm/boot/dts/*.dts* | wc -l
2105

$ git grep -P --name-only '<\S+@\S+>' arch/arm/boot/dts/*.dts* | wc -l
997

Some have multiple email addresses:

$ git grep -P '<\S+@\S+>' arch/arm/boot/dts/*.dts* | wc -l
1240

(and there are a few false positives in that regex)

I suppose that get_maintainer could handle .dts* files
the same way .yaml files are handled so any email address
in the file is added to patches that touch the file.

This is the commit that added the .yaml file handling:

    get_maintainer: add email addresses from .yaml files
    
    .yaml files can contain maintainer/author addresses and it seems unlikely
    or unnecessary that individual MAINTAINER file section entries for each
    .yaml file will be created.
    
    So add the email addresses found in .yaml files to the default
    get_maintainer output.
    
    The email addresses are marked with "(in file)" when using the "--roles"
    or "--rolestats" options.

So something like:
