The spi-3wire property is device specific and should be accepted only if device really needs them. Drop it from common spi-peripheral-props.yaml schema, mention in few panel drivers which use it and include instead in the SPI controller bindings. The controller bindings will provide spi-3wire type validation and one place for description. Each device schema must list the property if it is applicable. The Samsung S6E63M0 panel uses also spi-cpha/cpol properties on at least one board (ste-ux500-samsung-janice/dts), so add also these to the panel's bindings.

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.
