[ Upstream commitb1ff1bfe81] There is no dedicate parent clock for QSPI so SET_RATE_PARENT flag should not be used. For instance, the default parent clock for QSPI is pll2_bus, which is also the parent clock for quite a few modules, such as MMDC, once GPMI NAND set clock rate for EDO5 mode can cause system hang due to pll2_bus rate changed.

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.
