Quoting Lina Iyer (2019-11-14 10:35:12) > When an interrupt is to be serviced, the convention is to mask the > interrupt at the chip and unmask after servicing the interrupt. Enabling > and disabling the interrupt at the PDC irqchip causes an interrupt storm > due to the way dual edge interrupts are handled in hardware. > > Skip configuring the PDC when the IRQ is masked and unmasked, instead > use the irq_enable/irq_disable callbacks to toggle the IRQ_ENABLE > register at the PDC. The PDC's IRQ_ENABLE register is only used during > the monitoring mode when the system is asleep and is not needed for > active mode detection. > > Signed-off-by: Lina Iyer <ilina@xxxxxxxxxxxxxx> > --- Reviewed-by: Stephen Boyd <swboyd@xxxxxxxxxxxx>
