with this version my board can finally wake up again. Although it wakes
immediatly again. But as it wakes at all, I'm quite happy :-) .

I remember this being mentioned before, but I don't remember what was
responsible for that. Was it because we only enter the light suspend mode
instead of the deep one or some interrupt somewhere?


I've been running on top of linux-next from 20141124 with the following
patches applied on top of your v8 series:

pinctrl: rockchip: Fix enable/disable/mask/unmask
pinctrl: rockchip: Handle wakeup pins
serial: 8250_dw: Handle no_console_suspend when uart loses state
