From 74c6836db73c9361c34dcc9dfd363f5b447d1b30 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Sat, 1 Jul 2017 15:16:36 +0100 Subject: [PATCH 03/13] ARM64: dts: marvell: armada37xx: Wire PMUv3 The Cortex-A53s that power the Armada-37xx SoCs are equipped with a PMUv3, just like most ARMv8 cores. Advertise the PMUv3 presence in the device tree, and wire its interrupt. This allows the perf subsystem to work correctly.
