[ Upstream commit0f1c806b65] The systimer block derives its 13 MHz clock by dividing the main 26 MHz oscillator clock by 2 internally, not through the TOPCKGEN clock controller. On the MT8195 this divider is set either by power-on-reset or by the bootloader. The bootloader may then make the divider unconfigurable to, but can be read out by, the operating system. Making the systimer block take the 26 MHz clock directly requires changing the implementations. As an ABI compatible fix, change the input clock of the systimer block a fixed factor divide-by-2 clock that takes the 26 MHz oscillator as its input.

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.
