Freescale CoreNet Coherency Fabric(CCF) Device Tree Binding

DESCRIPTION

The CoreNet coherency fabric is a fabric-oriented, connectivity infrastructure
that enables the implementation of coherent, multicore systems.

Required properties:

  • compatible:

      fsl,corenet1-cf - CoreNet coherency fabric version 1.
      Example chips: T4240, B4860
    
      fsl,corenet2-cf - CoreNet coherency fabric version 2.
      Example chips: P5040, P5020, P4080, P3041, P2041
    
      fsl,corenet-cf - Used to represent the common registers
      between CCF version 1 and CCF version 2.  This compatible
      is retained for compatibility reasons, as it was already
      used for both CCF version 1 chips and CCF version 2
      chips.  It should be specified after either
      "fsl,corenet1-cf" or "fsl,corenet2-cf".
    
  • reg:

      A standard property. Represents the CCF registers.
    
  • interrupts:

      Interrupt mapping for CCF error interrupt.
    
  • fsl,ccf-num-csdids:

      Specifies the number of Coherency Subdomain ID Port Mapping
      Registers that are supported by the CCF.
    
  • fsl,ccf-num-snoopids:

      Specifies the number of Snoop ID Port Mapping Registers that
      are supported by CCF.
    

Example:

corenet-cf@18000 {
    compatible = "fsl,corenet2-cf", "fsl,corenet-cf";
    reg = <0x18000 0x1000>;
    interrupts = <16 2 1 31>;
    fsl,ccf-num-csdids = <32>;
    fsl,ccf-num-snoopids = <32>;
};
