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 Heiko -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
