From 257d0e20ec4f94e33ac463b918fb82bb1b2dcbe0 Mon Sep 17 00:00:00 2001 From: Lukasz Luba Date: Tue, 17 Dec 2019 13:43:44 +0000 Subject: include: trace: Add SCMI header with trace events Adding trace events would help to measure the speed of the communication channel. It can be also potentially used helpful during investigation of some issues platforms which use different transport layer. Update also MAINTAINERS file with information that the new trace events are maintained.
