The problem is that the big and LITTLE cores have different ordering per SoCs: - Exynos5420 and Exynos5800: cpu0-3 (Cortex-A15) and cpu4-7 (Coretx-A7) - Exynos5422: cpu0-3 (Cortex-A7) and cpu4-7 (Cortex-A15) So the OPP tables are set in this DTSI file, to prevent the OPP tables in the Exynos5422 to be inverted for the cluster 0 and 1.
