mainlining shenanigans
d4706c05c5
Newer cp210x devices support higher line speeds than the older ones which supported a discrete set of speeds up to 921.6 kbaud. To support these higher speeds, we have for some time mapped speeds lower than 1 Mbaud to the speeds supported by older devices, while allowing the device to pick the closest possible rate for higher speeds (without trying to guess and report back what rate was actually chosen). As this implementation can lead to undefined behaviour for older devices which do not support the higher rates, let's use the later-added device-type detection to determine the maximum supported speed. This will also be useful when adding support for cp2102n which can handle rates up to 3 Mbaud. As per the data sheets the following maximum speeds are used cp2101 921.6 kbaud cp2102/3 1 Mbaud cp2104/8 2 Mbaud cp2105 - ECI port 2 Mbaud - SCI port 921.6 kbaud while keeping the maximum 2 Mbaud for unknown device types in order to avoid any regressions.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
