From 7dcdad6f32c96af6e6fb2afe83ec4028dbe1da44 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Tue, 23 May 2023 11:52:48 +0200 Subject: [PATCH] interconnect: drop unused icc_get() interface The icc_get() interface can be used to lookup an interconnect path based on global node ids. There has never been any users of this interface and all lookups are currently done from the devicetree. Remove the unused icc_get() interface.
