| 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. |
