Exynos5420 is an octacore SoC. This patch series enables the remaining 4 cores.
Changes in v2:
- Changed the cpu node @unit-address value to reg property value.
Chander Kashyap (2):
clocksource: mct: extend mct to support 8 local interrupts for
Exynos5420
arm: dt: Exynos5420: populate cpu node enteries to 8 cpus
