+
+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.
+
+PROPERTIES
+
+ - 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.
+
+ - fsl,num-laws
+ Usage: required
+ Value type: <u32>
+ Definition: The value specifies the number of local access

+MPX Coherency Module Node
+
+The MPX LAW node represents the region of CCSR space where MCM config
