Subject: [PATCH 9/9] arm64: dts: exynos: Add cpu topology information for
Exynos5433 SoC
This patch adds the 'cpu-map' for the cpu topology information
of Exynos5433 which has the following two clusters.
- cluster0 contains the four LITTLE cores (cpu0-3).
- cluster1 contains the four big cores (cpu4-7).
