Subject: [PATCH v4 06/10] arm64: dts: apple: Add t8103 PMU interrupt affinities
Date: Mon, 24 Jan 2022 20:12:27 +0000 [thread overview]
Message-ID: <20220124201231.298961-7-maz@kernel.org> (raw)
In-Reply-To: <20220124201231.298961-1-maz@kernel.org>
The two PMU pseudo interrupts have specific affinities. One set
is affine to the small cores, and the other set affine to the
big ones.
