E500 LAW & Coherency Module Device Tree Binding
Copyright (C) 2009 Freescale Semiconductor Inc.
=====================================================================
Local Access Window (LAW) Node
The LAW node represents the region of CCSR space where local access
windows are configured. For ECM 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,ecm-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
windows for this device.
=====================================================================
E500 Coherency Module Node
The E500 LAW node represents the region of CCSR space where ECM config
and error reporting registers exist, this is the second 4k (0x1000)
of CCSR space.
PROPERTIES
- compatible
Usage: required
Value type: <string>
Definition: Must include "fsl,CHIP-ecm", "fsl,ecm" where
CHIP is the processor (mpc8572, mpc8544, etc.)
- 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.
- interrupts
Usage: required
Value type: <prop-encoded-array>
- interrupt-parent
Usage: required
Value type: <phandle>
