Subject: [PATCH] arm64: dts: allwinner: a64: Drop PMU node
Date: Tue, 6 Aug 2019 07:01:35 -0700 [thread overview]
Message-ID: <20190806140135.4739-1-anarsoul@gmail.com> (raw)
Looks like PMU in A64 is broken, it generates no interrupts at all and
as result 'perf top' shows no events.
Tested on Pine64-LTS.
Fixes: 34a97fcc71c2 ("arm64: dts: allwinner: a64: Add PMU node")
