Subject: [PATCH] ARM: vexpress: Remove A9 PMU compatible values for non-A9 platforms
Date: Tue, 9 Apr 2013 14:17:50 +0100 [thread overview]
Message-ID: <1365513470-2680-1-git-send-email-pawel.moll@arm.com> (raw)
The ARM perf core code used to rely on the pmu node being
compatible with "arm,cortex-a9-pmu", even when the PMUs
of the different Cortex-A processors are not really
compatible... This is no longer required and actually
became harmful, so remove all the offending values
from Versatile Express DTS files.
