The l13a rail on trogdor devices has always been intended to be always-on on both S0 and S3. Different trogdor variants use l13a in slightly different ways, but the overall theme is that it's a 1.8V rail that the board uses for things that it wants powered in on S0 and S3. On many boards this includes the boot SPI (AKA qspi). For all intents and purposes this patch is actually a no-op since something else in the system seems to already be keeping the rail on all the time (confirmed via multimeter). That "something else" was postulated to be the modem but the rail is on / stays on even without the modem/wifi coming up so it's likely the boot config. In any case, making the fact that this is always-on explicit seems like a good idea.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
