DWC3 variant found in Exynos5433 SoCs requires keeping all DRD30/UHOST30 clocks enabled all the time the driver does any access to DWC3 registers, otherwise external abort happens. So far DWC3 hardware module worked with samsung,exynos5250-dwusb3 compatible only by luck when built into kernel: all DRD30 clocks were left enabled by bootloader and later kept enabled by the DRD PHY driver. However, if one tried to use Exnos DWC3 driver as a module or performed system suspend/resume cycle, external abort happened. This patch finally fixes this issue.

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.
