Krzysztof Kozlowski 61bed86699 ARM: dts: exynos: fix USB 3.0 pins supply being turned off on Odroid XU
commit bd7e7ff56f upstream.

On Odroid XU LDO12 and LDO15 supplies the power to USB 3.0 blocks but
the GPK GPIO pins are supplied by LDO7 (VDDQ_LCD).  LDO7 also supplies
GPJ GPIO pins.

The Exynos pinctrl driver does not take any supplies, so to have entire
GPIO block always available, make the regulator always on.

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.
