Applied.

Git tip: for future reference, set 'git config diff.renames true' so and
the diffstat shows a better summary when files are moved/renamed.

e.g, rather than the large ++ and -- above, you'd see:

 ...gxl-s905d-p23x.dtsi => meson-gx-p23x-q20x.dtsi} |   4 +-
 
Which is much more comforting to a maintainer than a bunch of
(potentially unrelated) adds and removes.

Thanks,

Kevin
