Add of_pci_preserve_config() to look for the "linux,pci-probe-only" property under a specified node. If it's not found there, look under "of_chosen" in addition. If the caller didn't specify a node, look under "of_chosen". With a future patch, this will support "linux,pci-probe-only" on a per host bridge basis based on the presence of the property in the respective PCI host bridge DT node. Implement of_pci_check_probe_only() using of_pci_preserve_config().

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.
