0001 Freescale CoreNet Coherency Fabric(CCF) Device Tree Binding
0002
0003 DESCRIPTION
0004
0005 The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure
0006 that enables the implementation of coherent, multicore systems.
0007
0008 Required properties:
0009
0010 - compatible: <string list>
0011 fsl,corenet1-cf - CoreNet coherency fabric version 1.
0012 Example chips: T4240, B4860
0013
0014 fsl,corenet2-cf - CoreNet coherency fabric version 2.
0015 Example chips: P5040, P5020, P4080, P3041, P2041
0016
0017 fsl,corenet-cf - Used to represent the common registers
0018 between CCF version 1 and CCF version 2. This compatible
0019 is retained for compatibility reasons, as it was already
0020 used for both CCF version 1 chips and CCF version 2
0021 chips. It should be specified after either
0022 "fsl,corenet1-cf" or "fsl,corenet2-cf".
0023
0024 - reg: <prop-encoded-array>
0025 A standard property. Represents the CCF registers.
0026
0027 - interrupts: <prop-encoded-array>
0028 Interrupt mapping for CCF error interrupt.
0029
0030 - fsl,ccf-num-csdids: <u32>
0031 Specifies the number of Coherency Subdomain ID Port Mapping
0032 Registers that are supported by the CCF.
0033
0034 - fsl,ccf-num-snoopids: <u32>
0035 Specifies the number of Snoop ID Port Mapping Registers that
0036 are supported by CCF.
0037
0038 Example:
0039
0040 corenet-cf@18000 {
0041 compatible = "fsl,corenet2-cf", "fsl,corenet-cf";
0042 reg = <0x18000 0x1000>;
0043 interrupts = <16 2 1 31>;
0044 fsl,ccf-num-csdids = <32>;
0045 fsl,ccf-num-snoopids = <32>;
0046 };
