Current name of coresight component's folder consists of prefix of the device and the id in the device list. When run 'ls' command, we can get the register address of the device. Take CTI for example, if we want to set the config for modem CTI, but we can't know which CTI is modem CTI from all current information. cti_sys0 -> ../../../devices/platform/soc@0/138f0000.cti/cti_sys0 cti_sys1 -> ../../../devices/platform/soc@0/13900000.cti/cti_sys1 Add device-name in device tree which can provide a better description of the coresight device. It can provide the info like the system or HW it belongs to.
