Enable devices on the 'cxl' bus to be attached to drivers. The initial user of this functionality is a driver for an 'nvdimm-bridge' device that anchors a libnvdimm hierarchy attached to CXL persistent memory resources. Other device types that will leverage this include: cxl_port: map and use component register functionality (HDM Decoders) cxl_nvdimm: translate CXL memory expander endpoints to libnvdimm 'nvdimm' objects cxl_region: translate CXL interleave sets to libnvdimm 'region' objects The pairing of devices to drivers is handled through the cxl_device_id() matching to cxl_driver.id values. A cxl_device_id() of '0' indicates no driver support. In addition to ->match(), ->probe(), and ->remove() support for the 'cxl' bus introduce MODULE_ALIAS_CXL() to autoload modules containing cxl-drivers. Drivers are added in follow-on changes.

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 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.
