Indeed there is no point in detecting the SPI peripheral device parameters and initializing the CR0 register fields each time an SPI transfer is executed. Instead let's define a dedicated CR0 chip-data member, which will be initialized in accordance with the SPI device settings at the moment of setting it up. By doing so we'll finally make the SPI device chip_data serving as it's supposed to - to preserve the SPI device specific DW SPI configuration. See spi-fsl-dspi.c, spi-pl022.c, spi-pxa2xx.c drivers for example of the way the chip data is utilized.

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.
