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. Heiko

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. Signed-off-by: Caesar Wang <wxt@rock-chips.com> --- 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. arch/arm64/boot/dts/rockchip/rk3368.dtsi | 6 ++++++ 1 file changed, 6 insertions(+)
