Subject: [PATCH v5 02/10] dt-bindings: apple,aic: Add CPU PMU per-cpu pseudo-interrupts
Date: Tue,  8 Feb 2022 18:55:56 +0000	[thread overview]
Message-ID: <20220208185604.1097957-3-maz@kernel.org> (raw)
In-Reply-To: <20220208185604.1097957-1-maz@kernel.org>

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.
