Anson Huang 1bfe610491 ARM: dts: imx7ulp-evk: Use APLL_PFD1 as usdhc's clock source i.MX7ULP does NOT support runtime switching clock source for PCC, APLL_PFD1 by default is usdhc's clock source, so just use it in kernel to avoid below kernel dump during kernel boot up and make sure kernel can boot up with SD root file-system.

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.
