Hello,
This small patch series intends to add support for the PMU of the
Cortex-A72 cores found in the Marvell Armada 7K/8K SoCs.
However, the interrupt of the PMU is not directly connected to the
GIC, but goes through a secondary interrupt controller called the
PIC. Therefore, this series starts by adding a small driver for this
interrupt controller, before enabling the PIC and the PMU in the
Device Tree.
Thanks!
Thomas
