Subject: [PATCH v4 02/10] dt-bindings: apple, aic: Add CPU PMU per-cpu pseudo-interrupts

From: Marc Zyngier <[email-masked]>
Date: Mon, 24 Jan 2022 20:12:23 +0000

Advertise the two pseudo-interrupts that tied to the two PMU
flavours present in the Apple M1 SoC.

We choose the expose two different pseudo-interrupts to the OS
as the e-core PMU is obviously different from the p-core one,
effectively presenting two different devices.
