Driver providing perf backend for ARM Cache Coherent Network interconnect. Supports counting all hardware events and crosspoint watchpoints. Currently works with CCN-504 only, although there should be no changes required for CCN-508 (just impossible to test it now).

|
|
|
- compatible: (standard compatible string) should be one of:
|
|
"arm,ccn-504"
|
|
"arm,ccn-508"
|
|
|
|
- reg: (standard registers property) physical address and size
|
|
(16MB) of the configuration registers block
|
|
|
|
- interrupts: (standard interrupt property) single interrupt
|
|
generated by the control block

Example:
|
|
|
|
ccn@0x2000000000 {
|
|
compatible = "arm,ccn-504";
|
|
reg = <0x20 0x00000000 0 0x1000000>;
|
|
interrupts = <0 181 4>;
