On new LPUART versions, the oversampling ratio for the receiver can be changed from 4x (00011) to 32x (11111) which could help us get a more accurate baud rate divider. The idea is to use the best OSR (over-sampling rate) possible. Note, OSR is typically hard-set to 16 in other LPUART instantiations. Loop to find the best OSR value possible, one that generates minimum baud diff iterate through the rest of the supported values of OSR.

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.
