Subject: arm64: dts: apple: Add t8103 PMU interrupt affinities
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1852e22b318b8d1c02b574da679b1b74f3686090;p=linux.git

arm64: dts: apple: Add t8103 PMU interrupt affinities

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.
