X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=395e66ba07aaec5ce37b61da158816d96d4b3ce1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM64: dts: marvell: armada-37xx: 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.
