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