5 ARM multi-cluster systems maintain intra-cluster coherency through a
10 clusters, through memory mapped interface, with a global control register
11 space and multiple sets of interface control registers, one per slave
12 interface.
14 * CCI interconnect node
18 Node name must be "cci".
19 Node's parent must be the root node /, and the address space visible
21 root node (ie from CPUs perspective as per DT standard).
22 Every CCI node has to define the following properties:
24 - compatible
28 "arm,cci-400"
29 "arm,cci-500"
30 "arm,cci-550"
32 - reg
40 - ranges:
48 interfaces addresses refer to the parent node
51 CCI interconnect node can define the following child nodes:
53 - CCI control interface nodes
55 Node name must be "slave-if".
56 Parent node must be CCI interconnect node.
58 A CCI control interface node must contain the following
61 - compatible
65 "arm,cci-400-ctrl-if"
67 - interface-type:
70 Definition: must be set to one of {"ace", "ace-lite"}
71 depending on the interface type the node
74 - reg:
80 corresponding interface programming
83 - CCI PMU node
85 Parent node must be CCI interconnect node.
87 A CCI pmu node must contain the following properties:
89 - compatible
93 "arm,cci-400-pmu,r0"
94 "arm,cci-400-pmu,r1"
95 "arm,cci-400-pmu" - DEPRECATED, permitted only where OS has
97 "arm,cci-500-pmu,r0"
98 "arm,cci-550-pmu,r0"
99 - reg:
105 corresponding interface programming
108 - interrupts:
112 ../interrupt-controller/interrupts.txt.
129 A CCI interconnect bus master node must contain the following
132 - cci-control-port:
135 Definition: a phandle containing the CCI control interface node
