Subject[PATCH 5.3 007/140] arm64: dts: allwinner: a64: Drop PMU node
Date
From: Vasily Khoruzhick <anarsoul@gmail.com>

[ Upstream commit ed3e9406bcbc32f84dc4aa4cb4767852e5ab086c ]

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.
