It is needed for IRQCHIP_MASK_ON_SUSPEND operation, which in turn is needed for Suspend-to-RAM. >> Also extend the code to set IRQCHIP_MASK_ON_SUSPEND which tells the core >> that only IRQs marked as wakeups need to stay enabled during Suspend-to-RAM. > > Shouldn't this be split to a separate patch ? I could split them up, but since there is a dependency and since I mainly care about making sure Suspend-to-RAM works I preferred to keep them together. >> Tested on the Lager board with GPIO-keys and Suspend-to-RAM. >> >> Signed-off-by: Magnus Damm <d...@opensource.se> >> --- >> >> drivers/gpio/gpio-rcar.c | 3 +-- >> 1 file changed, 1 insertion(+), 2 deletions(-) >> >> --- 0001/drivers/gpio/gpio-rcar.c >> +++ work/drivers/gpio/gpio-rcar.c 2013-11-13 19:26:26.000000000 +0900 >> @@ -368,10 +368,9 @@ static int gpio_rcar_probe(struct platfo >> irq_chip->name = name; >> irq_chip->irq_mask = gpio_rcar_irq_disable; >> irq_chip->irq_unmask = gpio_rcar_irq_enable; >> - irq_chip->irq_enable = gpio_rcar_irq_enable; >> - irq_chip->irq_disable = gpio_rcar_irq_disable; >> irq_chip->irq_set_type = gpio_rcar_irq_set_type; >> irq_chip->flags = IRQCHIP_SKIP_SET_WAKE | IRQCHIP_SET_TYPE_MASKED; >> + irq_chip->flags |= IRQCHIP_MASK_ON_SUSPEND; > > You can write it as > > irq_chip->flags = IRQCHIP_SKIP_SET_WAKE | IRQCHIP_SET_TYPE_MASKED > | IRQCHIP_MASK_ON_SUSPEND; I know. =) If that's the preferred way then..
