Instead of passing a global GPIO number for the enable GPIO, pass a descriptor looked up from the device tree node or the board file decriptor table for the regulator. There is a single board file passing the GPIOs for LDO1 and LDO2 through platform data, so augment this to pass descriptors associated with the i2c device as well. The special GPIO enable DT property for the enable GPIO is nonstandard but this was accomodated in commit 6a537d48461deacc57c07ed86d9915e5aa4b3539 "gpio: of: Support regulator nonstandard GPIO properties".

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.
