On boot, the clock divider value is 0 which is a weird unsupported value. For example, accessing the cfg register with this value set would crash the SoC. Previous change removed 0 as possible value for CCF but forgot to properly initialize the register before registering the clock. This leads to the CCF finding an illegal value, which it complains about. Initialize the register properly in a standalone patch so the fix can be picked up if necessary. The change this fixed is: "mmc: meson-gx: remove CLK_DIVIDER_ALLOW_ZERO clock flag".

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
