In the i.MX6QP sabresd board(sch-28857) design, one external oscillator is powered up by vgen3 and used as the PCIe reference clock source by the endpoint device. If RC uses this oscillator as reference clock too, PLL6(ENET PLL) would has to be in bypass mode, and ENET clocks would be messed up. To keep things simple, let RC use the internal PLL as reference clock and set vgen3 always on to enable the external oscillator for endpoint device on i.MX6QP sabresd board. NOTE: This reference clock setup is used to pass the GEN2 TX compliance tests, and isn't recommended as a setup in the end-user design.

README
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.
