1 ===================================================================== 2 MPX LAW & Coherency Module Device Tree Binding 3 Copyright (C) 2009 Freescale Semiconductor Inc. 4 ===================================================================== 5 6 Local Access Window (LAW) Node 7 8 The LAW node represents the region of CCSR space where local access 9 windows are configured. For MCM based devices this is the first 4k 10 of CCSR space that includes CCSRBAR, ALTCBAR, ALTCAR, BPTR, and some 11 number of local access windows as specified by fsl,num-laws. 12 13 PROPERTIES 14 15 - compatible 16 Usage: required 17 Value type: <string> 18 Definition: Must include "fsl,mcm-law" 19 20 - reg 21 Usage: required 22 Value type: <prop-encoded-array> 23 Definition: A standard property. The value specifies the 24 physical address offset and length of the CCSR space 25 registers. 26 27 - fsl,num-laws 28 Usage: required 29 Value type: <u32> 30 Definition: The value specifies the number of local access 31 windows for this device. 32 33 ===================================================================== 34 35 MPX Coherency Module Node 36 37 The MPX LAW node represents the region of CCSR space where MCM config 38 and error reporting registers exist, this is the second 4k (0x1000) 39 of CCSR space. 40 41 PROPERTIES 42 43 - compatible 44 Usage: required 45 Value type: <string> 46 Definition: Must include "fsl,CHIP-mcm", "fsl,mcm" where 47 CHIP is the processor (mpc8641, mpc8610, etc.) 48 49 - reg 50 Usage: required 51 Value type: <prop-encoded-array> 52 Definition: A standard property. The value specifies the 53 physical address offset and length of the CCSR space 54 registers. 55 56 - interrupts 57 Usage: required 58 Value type: <prop-encoded-array> 59 60 =====================================================================
