[ Upstream commit 06b2818678d9b35102c9816ffaf6893caf306ed0 ]
This might be a limitation of either the current panfrost driver
devfreq implementation or how the gpu is implemented in RK3399 SoC.
The gpu regulator must never get disabled or the registers get
(randomly?) inaccessable by the driver. (see all other RK3399 boards)
Fixes: ec7d731d81e7 ("arm64: dts: rockchip: Add node for gpu on rk3399-roc-pc")

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.
