applied this patch to my dts64 branch for 4.5 .

The Kconfig option will probably need to wait for 4.6 though, due to the 
clocksource change going through Daniel's tree. Or I'll try to submit that 
post 4.5-rc1 as "fix" ... we'll see.

[PATCH v2 4/4] arm64: dts: rockchip: Add the needed timer for RK3368 SoC

[Caesar Wang]

There is a need of a broadcast timer in this case to ensure proper
wakeup when the cpus are in sleep mode and a timer expires.

Changes in v2: None
Changes in v1:
- As the Heiko comments, add the "rockchip,rk3368-timer" for timer.
  Although the 'rockchip,rk3288-timer' is working for RK3368, need to add the
  'rockchip,rk3368-timer' for the rk3368-spec timer in the future.
