+Contact:	linux-kernel@vger.kernel.org
+Description:
+		The /sys/class/scrub/scrubX/region{0,1,2,3,...}
+		directories correspond to each scrub region under a scrub device.
+		Scrub region is a physical address range for which scrub may be
+		separately controlled. Regions may overlap in which case the
+		scrubbing rate of the overlapped memory will be at least that
+		expected due to each overlapping region.

+What:		/sys/class/scrub/scrubX/regionY/addr_base
+Date:		November 2023
+KernelVersion:	6.8
+Contact:	linux-kernel@vger.kernel.org
+Description:
+		(RW) The base of the address range of the memory region
+		to be scrubbed.
+		On reading, returns the base of the memory region for
+		the actual address range(The platform calculates
+		the nearest patrol scrub boundary address from where
+		it can start scrub).

+		and it must be with in the supported range by the scrub.
