DT schema expects TLMM pin configuration nodes to be named with '-state' suffix and their optional children with '-pins' suffix. Merge subnodes named 'pinconf' and 'pinmux' into one entry, add function where missing (required by bindings for GPIOs) and reorganize overriding pins by boards. Split the SPI and UART configuration into separate nodes 1. SPI (MOSI, MISO, SCLK), SPI chip-select, SPI chip-select via GPIO, 2. UART per each pin: TX, RX and optional CTS/RTS. This allows each board to customize them easily without adding any new nodes.

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.
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.
