      5Description:
      6		(RO) Size of a write request to a DIMM that will not incur a
      7		read-modify-write cycle at the memory controller.
      8
      9		When the nfit driver initializes it runs an ARS (Address Range
     10		Scrub) operation across every pmem range. Part of that process
     11		involves determining the ARS capabilities of a given address
     12		range. One of the capabilities that is reported is the 'Clear
     13		Uncorrectable Error Range Length Unit Size' (see: ACPI 6.2
     14		section 9.20.7.4 Function Index 1 - Query ARS Capabilities).
     15		This property indicates the boundary at which the NVDIMM may
     16		need to perform read-modify-write cycles to maintain ECC (Error
     17		Correcting Code) blocks.
