The H3 ES1.x exhibits dot clock duty cycle stability issues. We can work around them by configuring the DPLL to twice the desired frequency, coupled with a /2 post-divider. This isn't needed on other SoCs and breaks HDMI output on M3-W for a currently unknown reason, so restrict the workaround to H3 ES1.x. From an implementation point of view, move work around handling outside of the rcar_du_dpll_divider() function by requesting a x2 DPLL output frequency explicitly. The existing post-divider calculation mechanism will then take care of dividing the clock by two automatically. While at it, print a more useful debugging message to ease debugging clock rate issues.

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.
