The alpha value calculation has been written for 40-bit alpha values which doesn't work work properly for 16-bit ones. The alpha value is calculated on the basis of ALPHA_BITWIDTH to make the computation easy for 40 bit alpha. After calculating the 32 bit alpha, it is converted to 40 bit alpha by making lower bits zero. But if actual alpha register width is less than ALPHA_BITWIDTH, then the actual width can be used for calculation. This also means, during the 40 bit alpha pll set rate path, the lower alpha register is not configured Change the code to calculate the rate and register values from 'alpha_width' instead of hard-coding it so that it can work for the different widths that are supported.

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.
