    ARM: dts: Fix omap serial wake-up when booted with device tree · 31f0820a
    Tony Lindgren authored
    We've had deeper idle states working on omaps for few years now,
    but only in the legacy mode. When booted with device tree, the
    wake-up events did not have a chance to work until commit
    3e6cee17 (pinctrl: single: Add support for wake-up interrupts)
    that recently got merged. In addition to that we also needed commit
    79d97015 (of/irq: create interrupts-extended property) and
    9ec36caf (of/irq: do irq resolution in platform_get_irq) that
    are now also merged.
    
    So let's fix the wake-up events for some selected omaps so devices
    booted in device tree mode won't just hang if deeper power states
    are enabled, and so systems can wake up from suspend to the serial
    port event.
    
    Note that there's no longer need to specify the wake-up bit in
    the pinctrl settings, the request_irq on the wake-up pin takes
    care of that.
