With current design, the name of the non-cpu bounded coresight component is the device type with the number. And with 'ls' command we can get the register address of the component. But from these information, we can't know what the HW or system the component belongs to. Add device-name in DT to support it.
cti_sys0 -> ../../../devices/platform/soc@0/138f0000.cti/cti_sys0 cti_sys1 -> ../../../devices/platform/soc@0/13900000.cti/cti_sys1 tpdm0 -> ../../../devices/platform/soc@0/10b0d000.tpdm/tpdm0 tpdm1 -> ../../../devices/platform/soc@0/10c28000.tpdm/tpdm1 tpdm2 -> ../../../devices/platform/soc@0/10c29000.tpdm/tpdm2
Change since V3: 1. Change device-name to arm,cs-dev-name. 2. Add arm,cs-dev-name to only CTI and sources' dt-binding.
Change since V2: 1. Fix the error in coresight core. drivers/hwtracing/coresight/coresight-core.c:1775:7: error: assigning to 'char *' from 'const char *' discards qualifiers
2. Fix the warning when run dtbinding check. Documentation/devicetree/bindings/arm/arm,coresight-cpu-debug.yaml: device-name: missing type definition
Change since V1: 1. Change coresight-name to device name. 2. Add the device-name in coresight dt bindings.
