Input source 0 of the mmc controllers is not directly xtal, as currently described in DT. Each controller is fed by a composite clock (the usual mux, divider and gate). The muxes inputs are the xtal (default) and the fclk_div clocks. These parents, along with the divider, should be able to provide the necessary rates for mmc and nand operation. The input muxes should also be able to take mpll2, mpll3 and gp0_pll but these are precious clocks, needed for other usage. It is better if the mmc does not use these them. For this reason, mpll2, mpll3 and gp0_pll is not listed among the possible parents. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
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.
