Modern device tree bindings are supposed to be created as YAML-files in accordance with dt-schema. This commit replaces two DW SPI legacy bare text bindings with YAML file. As before the bindings file states that the corresponding dts node is supposed to be compatible either with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel vendors-specific controllers, to have registers, interrupts and clocks properties. Though in case of Microsemi version of the controller there must be two registers resources specified. Properties like clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device sub-nodes are optional.

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.
