Subject: [PATCH 02/12] 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.
|
