The factors we've seen so far all had an offset of one. However, on the earlier Allwinner SoCs, some factors could have no offset at all, meaning that the value computed to reach the rate we want to use was the one we had to program in the registers. Implement an additional field for the factors that can have such an offset (linears, not based on a power of two) to specify that offset. This offset is not linked to the extremums that can be specified in those structures too. The minimum and maximum are representing the range of values we can use to try to compute the best rate. The offset comes later on when we want to set the best value in the registers. Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.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.
