Merge tag 'cxl-for-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull cxl updates from Dave Jiang:

 - Constify range_contains() input parameters to prevent changes

 - Add support for displaying RCD capabilities in sysfs to support lspci
   for CXL device

 - Downgrade warning message to debug in cxl_probe_component_regs()

 - Add support for adding a printf specifier '%pra' to emit 'struct
   range' content:
     - Add sanity tests for 'struct resource'
     - Add documentation for special case
     - Add %pra for 'struct range'
     - Add %pra usage in CXL code

 - Add preparation code for DCD support:
     - Add range_overlaps()
     - Add CDAT DSMAS table shared and read only flag in ACPICA
     - Add documentation to 'struct dev_dax_range'
     - Delay event buffer allocation in CXL PCI code until needed
     - Use guard() in cxl_dpa_set_mode()
     - Refactor create region code to consolidate common code
