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). Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
