During device mode initialization on certain QC targets, before the
runstop bit is set, sometimes it's observed that the GEVNTADR{LO/HI}
register write fails. As a result, GEVTADDR registers are still 0x0.
Upon setting runstop bit, DWC3 controller attempts to write the new
events to address 0x0, causing an SMMU fault and system crash.
This was initially observed on SM8450 and later reported on few
other targets as well. As suggested by Qualcomm HW team, clearing
the GUSB3PIPECTL.SUSPHY bit resolves the issue by preventing register
write failures. Address this by setting the snps,dis_u3_susphy_quirk
to keep the GUSB3PIPECTL.SUSPHY bit cleared. This change was tested
on multiple targets (SM8350, SM8450 QCS615 etc.) for over an year
and hasn't exhibited any side effects.

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 reStructuredText 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.
