+
+Local Access Window (LAW) Node
+
+The LAW node represents the region of CCSR space where local access
+windows are configured.  For MCM based devices this is the first 4k
+of CCSR space that includes CCSRBAR, ALTCBAR, ALTCAR, BPTR, and some
+number of local access windows as specified by fsl,num-laws.

+
+  - compatible
+      Usage: required
+      Value type: <string>
+      Definition: Must include "fsl,mcm-law"
+
+  - reg
+      Usage: required
+      Value type: <prop-encoded-array>
+      Definition: A standard property.  The value specifies the
+          physical address offset and length of the CCSR space
+          registers.
