Instead of passing a global GPIO number, pass a descriptor looked up with the standard devm_gpiod_get_index_optional() call. This driver has supported passing a LDO enable GPIO for years, yet this facility has never been put to use in the upstream kernel. If someone desires to put in place GPIO control for the LDOs, this can be done by adding a GPIO descriptor table in the MFD nexus in drivers/mfd/lp8788.c for the LDO device when spawning the MFD children, or using a board file.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
