This patch adds new Exynos5433 dtsi to support 64-bit Exynos5433 SoC based on
Octal core CPUs (quad Cortex-A57 and quad Cortex-A53). And Exynos5433 supports
PSCI (Power State Coordination Interface) v0.1.

This patch includes following dt node to support Exynos5433 SoC:
1. Octa core for big.LITTLE architecture
- Cortex-A53 LITTLE Quad-core
- Cortex-A57 big Quad-core
- Support PSCI v0.1

Back at v2 you mentioned that CPU_OFF wasn't working [1].

Do both CPU_ON and CPU_OFF work for all CPUs, including the boot CPU?

The CPU1 ~ CPU7 are well woking about CPU_ON/OFF.
CPU0 (boot CPU) is only well working for CPU_OFF.
But when I try to turn on the CPU0 after CPU_OFF, I failed it.

I take it CPUs boot at EL2?

The timer node should be moved under the root node. It doesn't live on
the bus; it's a component of the CPU.

OK. I'll move it according to your comment.

Thanks,
