From 1888d3ddc3d6a2511be86045cfb2e7ea5fc67c44 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Thu, 15 Feb 2018 18:51:41 +0000 Subject: drivers/bus: Move Arm CCN PMU driver The arm-ccn driver is purely a perf driver for the CCN PMU, not a bus driver in the sense of the other residents of drivers/bus/, so let's move it to the appropriate place for SoC PMU drivers. Not to mention moving the documentation accordingly as well.
