What project are these for? There is no such file in the kernel tree.
I think you've sent these patches to the wrong people and mailing lists.

Yeah, realized it just after sending my reply. It is for internal NXP list.
Had it been for open source U-boot, Author would have chosen
"u-boot@lists.denx.de" ?
But, I still believe Author did it unknowingly and we all should be
easy on him/her.

Oh, and... u-boot@linux.nxdi.nxp.com bounces because that domain is
not resolvable - I guess that is internal to NXP, and this patch
should have remained within NXP and not been posted publically.

So why is it copied to:
devicetree@vger.kernel.org - a kernel mailing list
linux-kernel@vger.kernel.org - the main kernel mailing list
linux-gpio@vger.kernel.org - the gpio driver kernel mailing list
linux-arm-kernel@lists.infradead.org - the ARM kernel mailing list
Given that it includes four kernel mailing lists (ok, devicetree
may be argued to have a wider application), then I don't think the
conclusion that "it's for u-boot, because there's _one_ u-boot
mailing list in the recipients" is particularly obvious.
The author really needs to state that up front if they're sending
it to a wide audeience, rather than leaving people to guess, thereby
potentially wasting their time.
Not only did Andrew review the patch as if it were for the kernel,
but I also wasted time on this as well when I double-took the
ifdefs, and wanted to check the current driver in the kernel.

These files looks to be from U-boot, and must be intended for U-boot
as I see U-boot mailing

From what I can tell, these patches are not for the kernel. The
filenames don't match th kernel layout.

This does not seem right. You would expect each sub arch to have a
subdirectory in arch/arm/include/asm/ when in fact none do.
