From e540920cf21c2764047b8a6ddaeaa0683624e46e Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 25 Sep 2014 17:40:14 +0900 Subject: [PATCH] ARM: dts: add CPU nodes for Exynos4 SoCs Recent patch by Tomasz Figa ("irqchip: gic: Fix core ID calculation when topology is read from DT") fixed GIC driver to filter cluster ID from values returned by cpu_logical_map() for SoCs having registers mapped without per-CPU banking making it is possible to add CPU nodes for Exynos4 SoCs. In case of Exynos SoCs these CPU nodes are also required by future changes adding initialization of cpuidle states in Exynos cpuidle driver through DT. Tested on Origen board (Exynos4210 SoC) and Trats2 (Exynos4412 SoC).
