1Freescale CoreNet Coherency Fabric(CCF) Device Tree Binding 2 3DESCRIPTION 4 5The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure 6that enables the implementation of coherent, multicore systems. 7 8Required properties: 9 10- compatible: <string list> 11 fsl,corenet1-cf - CoreNet coherency fabric version 1. 12 Example chips: T4240, B4860 13 14 fsl,corenet2-cf - CoreNet coherency fabric version 2. 15 Example chips: P5040, P5020, P4080, P3041, P2041 16 17 fsl,corenet-cf - Used to represent the common registers 18 between CCF version 1 and CCF version 2. This compatible 19 is retained for compatibility reasons, as it was already 20 used for both CCF version 1 chips and CCF version 2 21 chips. It should be specified after either 22 "fsl,corenet1-cf" or "fsl,corenet2-cf". 23 24- reg: <prop-encoded-array> 25 A standard property. Represents the CCF registers. 26 27- interrupts: <prop-encoded-array> 28 Interrupt mapping for CCF error interrupt. 29 30- fsl,ccf-num-csdids: <u32> 31 Specifies the number of Coherency Subdomain ID Port Mapping 32 Registers that are supported by the CCF. 33 34- fsl,ccf-num-snoopids: <u32> 35 Specifies the number of Snoop ID Port Mapping Registers that 36 are supported by CCF. 37 38Example: 39 40 corenet-cf@18000 { 41 compatible = "fsl,corenet2-cf", "fsl,corenet-cf"; 42 reg = <0x18000 0x1000>; 43 interrupts = <16 2 1 31>; 44 fsl,ccf-num-csdids = <32>; 45 fsl,ccf-num-snoopids = <32>; 46 };
