How about something along the lines of the following: A single controller can handle normal interrupts and wake-up interrupts independently, with a different numbering space. It is thus crucial to allow the driver for such a controller discriminate between the two. A simple way to do so is to tag the wake-up irqdomain with a "bus token" that indicates the wake-up domain. This slightly abuses the notion of bus, but also radically simplifies the design of such a driver. Between two evils, we choose the least damaging. > > Suggested-by: Stephen Boyd <swboyd@chromium.org> > Signed-off-by: Lina Iyer <ilina@codeaurora.org> > --- > include/linux/irqdomain.h | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/include/linux/irqdomain.h b/include/linux/irqdomain.h > index 35965f41d7be..05055bc992ab 100644 > --- a/include/linux/irqdomain.h > +++ b/include/linux/irqdomain.h > @@ -82,6 +82,7 @@ enum irq_domain_bus_token { > DOMAIN_BUS_NEXUS, > DOMAIN_BUS_IPI, > DOMAIN_BUS_FSL_MC_MSI, > + DOMAIN_BUS_WAKEUP, > }; > > /** > Thanks, M.
