   1 Freescale CoreNet Coherency Fabric(CCF) Device Tree Binding
   2
   3 DESCRIPTION
   4
   5 The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure
   6 that enables the implementation of coherent, multicore systems.
   7
   8 Required 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
  38 Example:
  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         };
