If the array is not present, assume all chip selects are native. This is the standard behavior for SPI masters configured via the device tree and the behavior of this driver as well when it is configured via device tree. This reduces platform data vs DT differences and allows most of the platform data based boards to remove their chip select arrays.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
