Not clear that that got much review... We have a defined way to indicate wakeup sources (which maybe didn't exist in 2014), why can't that be used? If a device can wakeup the system, I'd think we can just assume that the parent interrupt controller(s) can support that. In any case, I'm not going to stand in the way of this: Acked-by: Rob Herring <robh@kernel.org> > Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> > --- > .../bindings/interrupt-controller/brcm,bcm7038-l1-intc.txt | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/Documentation/devicetree/bindings/interrupt-controller/brcm,bcm7038-l1-intc.txt b/Documentation/devicetree/bindings/interrupt-controller/brcm,bcm7038-l1-intc.txt > index 2117d4ac1ae5..4eb043270f5b 100644 > --- a/Documentation/devicetree/bindings/interrupt-controller/brcm,bcm7038-l1-intc.txt > +++ b/Documentation/devicetree/bindings/interrupt-controller/brcm,bcm7038-l1-intc.txt > @@ -31,6 +31,11 @@ Required properties: > - interrupts: specifies the interrupt line(s) in the interrupt-parent controller > node; valid values depend on the type of parent interrupt controller > > +Optional properties: > + > +- brcm,irq-can-wake: If present, this means the L1 controller can be used as a > + wakeup source for system suspend/resume. > + > If multiple reg ranges and interrupt-parent entries are present on an SMP > system, the driver will allow IRQ SMP affinity to be set up through the > /proc/irq/ interface.

The BCM7038 L1 interrupt controller can be used as a wake-up interrupt controller on MIPS and ARM-based systems, document the brcm,irq-can-wake which has been "standardized" across Broadcom interrupt controllers.
