On some systems the cs42l43 has amplifiers attached to its SPI controller that are not properly defined in ACPI. Currently software nodes are added to support this case, however, the chip selects for these devices are specified using a hack. A software node is added with the same name as the pinctrl driver, as the look up was name based, this allowed the GPIO look up to return the pinctrl driver even though the swnode was not owned by it. This was necessary as the swnodes did not support directly linking to real firmware nodes. Since commit |

README
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 reStructuredText 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.
