[PATCH 4.19.y-cip 19/22] arm64: dts: renesas: r8a774a1: Add CPU topology on r8a774a1 SoC


Biju Das <biju.das@...>
 

commit 7b996955e514bd3639419c1e725bc3b69c96bd05 upstream.

This patch adds the "cpu-map" into r8a774a1 composed of multi-cluster. This
definition is used to parse the cpu topology.

Based on work by Gaku Inami <gaku.inami.xw@...> for r8a7796 SoC.
