Subject: ARM: omap2+: set IRQCHIP_SKIP_SET_WAKE for INTC interrupts.
X-Git-Tag: sz_beta4~15
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1d60988d85897ed4c0d18a0d2a32438d29176de9;p=pandora-kernel.git

ARM: omap2+: set IRQCHIP_SKIP_SET_WAKE for INTC interrupts.

Without an ->irq_set_wake() method in an irq_chip, calls to
enable_irq_wake() will fail.  This also causes these interrupts to not
be able to abort suspend (via check_wakeup_irqs() in late suspend.)

Currently, we don't implement ->irq_set_wake() for INTC interrupts
because they default to be wakeup enabled by setting the GRPSEL bits
in PM init.  Even though there is no ->irq_set_wake(), we want
enable_irq_wake() to succeed so these interrupts can abort suspend
when necessary.

To fix, set IRQCHIP_SKIP_SET_WAKE flag for all the INTC
interrupts which avoids trying to check irq_chip->irq_set_wake()
and failing when it doesn't exist.

Longer term, we need to implement ->irq_set_wake() for the INTC
which can manage the appropriate GRPSEL bits.
