Yes, that's what "in use in mainline" refers to:

$ git grep "cortex-a15-gic" -- arch/arm64/boot/dts/ | grep -v gic-400
arch/arm64/boot/dts/apm/apm-shadowcat.dtsi: compatible =
"arm,cortex-a15-gic";
arch/arm64/boot/dts/apm/apm-storm.dtsi: compatible = "arm,cortex-a15-gic";
arch/arm64/boot/dts/arm/foundation-v8.dts: compatible =
"arm,cortex-a15-gic", "arm,cortex-a9-gic";
arch/arm64/boot/dts/arm/rtsm_ve-aemv8a.dts: compatible =
"arm,cortex-a15-gic", "arm,cortex-a9-gic";
arch/arm64/boot/dts/nvidia/tegra132.dtsi: compatible = "arm,cortex-a15-gic";

Yeah, I don't care about backwards compatibility with downstream
kernels, they use weird compatible strings with spaces anyway.
