This reverts commite440e30e26because it is not a reliable way of fixing SPI CS glitch and it depends on specific Linux kernel pin controller driver behavior. This behavior of kernel driver was changed in commitb991f8c362("pinctrl: core: Handling pinmux and pinconf separately") thus effectively the DTS fix stopped being effective. Proper solution for the glitching SPI chip select must be implemented in the drivers, not via ordering of entries in DTS, and is already introduced in commitd21f4b7ffc("pinctrl: qcom: Avoid glitching lines when we first mux to output").

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.
