Neil Armstrong b2c7d6ce2d arm64: dts: meson-gxl-s805x: reduce initial Mali450 core frequency
[ Upstream commit b2037dafcf082cd24b88ae9283af628235df36e1 ]

When starting at 744MHz, the Mali 450 core crashes on S805X based boards:
 lima d00c0000.gpu: IRQ ppmmu3 not found
 lima d00c0000.gpu: IRQ ppmmu4 not found
 lima d00c0000.gpu: IRQ ppmmu5 not found
 lima d00c0000.gpu: IRQ ppmmu6 not found
 lima d00c0000.gpu: IRQ ppmmu7 not found

 Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

Reverting to a safer 666Mhz frequency on the S805X that doesn't use the
GP0 PLL makes it more stable.

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.
