Yes, it would, but not 'exclusively' by the get_maintainer.pl
script.

I don't believe an F: arch/arm64/boot/dts/freescale/*
pattern would be appropriate as there is already another
section with this path as a pattern.

ARM/FREESCALE LAYERSCAPE ARM ARCHITECTURE
M:	Shawn Guo <shawnguo@kernel.org>
M:	Li Yang <leoyang.li@nxp.com>
L:	linux-arm-kernel@lists.infradead.org (moderated for non-subscribers)
S:	Maintained
T:	git git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux.git
F:	arch/arm/boot/dts/ls1021a*
F:	arch/arm64/boot/dts/freescale/fsl-*
F:	arch/arm64/boot/dts/freescale/qoriq-*

I suggest perhaps just adding a more specific entry of

F:	arch/arm64/boot/dts/freescale/imx*

And just FYI:

F: entries should be preferred over N: entries as
filename collisions with other regex matches are common.

Controlling the mismatches as was done with the X: exclusion
for drivers/media/i2c/ may not scale if another filename
is added into the kernel tree that is not maintained by you
that matches either of the imx or mxs pattern.

It's not really a significant issue though you may get a few
patches for files you don't care about at some point.

cheers, Joe
