The Amlogic SM1 can set a dedicated clock frequency for each CPU core by having a dedicate tree for each core similar to the CPU0 tree. Like the DSU tree, a supplementaty mux has been added to use the CPU0 frequency instead. But since the cluster only has a single power rail and shares a single PLL, it's not worth adding 3 unsused clock tree, so we add only the mux to select the CPU0 clock frequency for each CPU1, CPU2 and CPU3 cores. They are set read-only because the early boot stages sets them to select the CPU0 input clock.

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.
