From dd018a9cf9108f9c7d924f6fe09aed745e78a67e Mon Sep 17 00:00:00 2001 From: Georgi Djakov Date: Thu, 28 Nov 2019 16:18:16 +0200 Subject: interconnect: Move internal structs into a separate file Move the interconnect framework internal structs into a separate file, so that it can be included and used by ftrace code. This will allow us to expose some more useful information in the traces.
